TVS Apache RTR 160 4V upgrades

• Set rider sag and preload for your weight

  Suspension & handling$0–$40 · ~1 h to fit

  A tape measure, a helper and the preload adjusters the bike already has.

  Bikes are sprung for a nominal 75–80 kg rider in nothing but leathers. Set sag first and half the complaints about a bike diving, wallowing or running out of travel go away for free — and you learn whether the springs are actually wrong before you buy any.

  Check before you order

  • — Static and rider sag targets from the service manual, not a forum
  • — How much preload range is left before the adjuster bottoms out
  • — Whether the shock has a remote hydraulic adjuster (loaded settings become a 10-second job)

• Tyres chosen for the surface you actually ride

  Tyres, wheels & brakes$150–$500 · ~2 h to fit

  A tyre pair matched to your real road/dirt split, in the load and speed rating the bike needs.

  The single biggest change you can make to how a bike steers, grips and stops, and the only upgrade you are forced to buy anyway. Most riders run a 50/50 tyre for a 90/10 life, or a sport tyre through a winter.

  Check before you order

  • — Load index and speed rating at least what the manual specifies, especially two-up
  • — Tube or tubeless construction, and whether the rear is available in your size
  • — Honest split: knobblies wear out in 3,000 km of tarmac and steer badly in the wet

• Frame sliders and axle sliders

  Protection & crash damage$60–$220 · ~1 h to fit

  Delrin or nylon pucks on frame and axle mounts that slide instead of digging in.

  The cheapest way to keep a low-side to plastics and a lever instead of a case, a radiator and a fork leg.

  Check before you order

  • — Cut-out or no-cut mounts, and whether the fairing needs drilling
  • — Bolt grade and length: a slider is only as good as what it bolts through

  Search for parts:Amazon

• Wrap-around hand guards

  Protection & crash damage$40–$180 · ~1 h to fit

  Alloy-bar guards bolted to the bar end and clamp, with plastic shells.

  They protect the levers and your knuckles in a fall and from branches, and they cut windchill and rain on the road. A snapped clutch lever is a walk home; a bar guard is $60.

  Check before you order

  • — Bar-end bolt or plug, and inner bar diameter for the insert
  • — Clearance to the tank, fairing and switchgear at full lock
  • — Handlebar-mounted mirrors and heated grip wiring often need rerouting

  Search for parts:Amazon

• Handlebar swap and risers

  Ergonomics & comfort$40–$250 · ~2 h to fit

  A bar with different rise, sweep and width, or 20–50 mm risers on the stock bar.

  Fixes the standing position on a dirt bike and the wrist and shoulder ache on a road bike, for less than the price of a tyre. It is the first thing to try for a tall rider.

  Check before you order

  • — Cable, hose and loom length — brake hoses are the usual limit at full lock
  • — Bar diameter (22 vs 28.6 mm) and whether your controls and guards fit it
  • — Clearance to the screen, tank and fairing at full lock

  Search for parts:Amazon

• Wide footpegs, lowered pegs and adjustable levers

  Ergonomics & comfort$70–$300 · ~2 h to fit

  Wider, sharper-toothed footpegs, a lowering bracket where legroom is short, and span-adjustable brake and clutch levers.

  Wide pegs stop your boot slipping and take the fatigue out of standing; 20 mm of peg drop opens up a cramped riding position more than a bar change; a lever you can actually reach with two fingers is a braking upgrade.

  Check before you order

  • — Lowered pegs move the brake pedal and shifter too — both need re-setting
  • — Cornering clearance on a road bike: pegs that hang lower touch down earlier
  • — Folding pegs with a proper stop, so they do not fold under your boot

• Tank bag and cockpit storage

  Luggage & load carrying$60–$250 · ~1 h to fit

  A magnetic, strap or lock-ring tank bag, plus a small bar or fork bag for what you need while moving.

  Documents, phone, snacks and a tyre gauge where you can reach them without stopping. Weight this far forward barely affects handling.

  Check before you order

  • — Plastic or alloy tanks need straps or a lock ring, not magnets
  • — It must not block the bars at full lock or your view of the dash

  Search for parts:Amazon

• Brake-light modulator and rear conspicuity

  Lighting & visibility$30–$150 · ~1 h to fit

  An LED tail-light or modulator that flashes briefly on braking, plus reflective tape on the panniers, rims and fork.

  Being rear-ended in traffic is a top-three urban crash, and the cheapest countermeasure on the whole bike is a light that gets noticed and tape that gets seen in a headlight.

  Check before you order

  • — Modulator legality varies by market — some allow flashing only above a certain rate
  • — LED tail lights can confuse older bulb-monitor circuits

  Search for parts:Amazon

• Louder horn

  Lighting & visibility$25–$120 · ~1 h to fit

  A twin-tone or air horn on a relay, so the current is not going through the stock switch.

  The stock horn on most bikes cannot be heard inside a car with the windows up. It is $40 to fix that.

  Check before you order

  • — Mounting point with airflow and no water trap
  • — Relay it: the stock wiring cannot carry an air horn

• Fused accessory block with USB

  Electrics & charging$30–$180 · ~3 h to fit

  A small fuse block fed from the battery through a relay triggered by an ignition-switched circuit, with USB and a powerlet outlet.

  One place to hang lights, heated kit, a GPS and a compressor, each individually fused, nothing draining the battery with the key out, and no more spliced-into-the-tail-light wiring.

  Check before you order

  • — Total accessory draw against what the alternator makes at idle
  • — A dry mounting spot with strain-relieved wiring away from the steering head
  • — Trigger the relay from a low-current circuit, not the headlight feed

  Search for parts:Amazon

• Navigation mount and powered cradle

  Electrics & charging$40–$200 · ~1 h to fit

  A vibration-damped mount on the bar clamp or a frame bracket, with a switched, fused power lead.

  Phones die from vibration on a bar clamp, and a phone on a dying battery is a navigation failure at the worst moment.

  Check before you order

  • — Mount off the bar clamp or a solid bracket, not mid-bar, and damped on a single-cylinder bike
  • — It must not obstruct the dash or the bars at full lock

  Do first: Fused accessory block with USB

  Search for parts:Amazon

• Voltmeter and a tender lead

  Electrics & charging$20–$90 · ~1 h to fit

  A dash or bar voltmeter, plus a permanently fitted pigtail for a smart charger.

  A charging fault shows up as a falling voltage days before it strands you, and a bike that lives outside stays healthy on a tender for the price of one battery.

  Check before you order

  • — Pigtail routed where you can reach it without removing bodywork
  • — Fused at the battery end

  Search for parts:Amazon

• Fastener audit and thread-lock

  Reliability & longevity$10–$80 · ~3 h to fit

  A torque wrench, the manual's torque table, medium-strength thread-lock and an evening.

  Half of all roadside failures are something that vibrated loose: subframe bolts, sprocket nuts, bar clamps, exhaust flanges, spokes. It costs the price of a bottle of thread-lock.

  Check before you order

  • — The manual's torque figures, since alloy threads strip long before steel
  • — Paint-mark critical fasteners so a loose one is visible at a glance

  Search for parts:Amazon

• Fluids and filters baseline

  Reliability & longevity$60–$250 · ~3 h to fit

  Engine oil and filter, brake fluid, coolant, air filter and fuel filter, all replaced to a known date regardless of what the seller said.

  On a used bike this is the cheapest way to reset the unknowns, and brake fluid and coolant are the two nobody ever changes.

  Check before you order

  • — Grades and quantities from the bike's own manual — never the brand default
  • — Off-road bikes need a foam-filter service kit and a spare filter, not just a new one

  Search for parts:Amazon

• Air filter and intake service

  Power & fuelling$30–$150 · ~1 h to fit

  A high-flow or correctly serviced filter, a clean airbox, and the snorkel or lid left alone unless the fuelling is being changed with it.

  A clogged filter costs real power and economy, and on a dirt bike it is the difference between an engine that lasts 200 hours and one that lasts 60. Removing an airbox lid without touching the fuelling usually makes the bike worse, not faster.

  Check before you order

  • — Foam filters need oiling correctly; a dry foam filter passes dust straight through
  • — Do not open up the intake unless the fuelling can be adjusted to match

• Shorter gearing

  Power & fuelling$70–$220 · ~2 h to fit

  One tooth down at the front or two up at the rear, and a chain adjusted or replaced to suit.

  The cheapest usable performance change there is: the bike feels considerably stronger everywhere you actually ride it, for the price of a sprocket.

  Trade-off: Higher cruising revs, worse economy, and more heat on a long highway leg.

  Check before you order

  • — Chain length and adjuster range
  • — Highway revs and fuel range both get worse — the reason to do the sums before the trip, not after
  • — Speedometer error, and on some bikes traction-control calibration

  Search for parts:Amazon

• Sintered pads and braided lines

  Tyres, wheels & brakes$80–$300 · ~2 h to fit

  Pads to a spec chosen for the use, stainless braided hoses and fresh fluid.

  Braided lines take the sponge out of a long front line, and fresh fluid does more than either. On a bike carrying luggage or a pillion the stock pad compound is usually the weak link, not the caliper.

  Check before you order

  • — Pad compound suits the disc: some sintered compounds chew cast-iron and older discs
  • — Hose lengths for your bar and mudguard setup, and whether ABS lines are separate
  • — Off-road: softer pads bite better cold and wet, but glaze under sustained downhill braking

• Reshaped or aftermarket seat

  Ergonomics & comfort$180–$600 · ~1 h to fit

  A wider, flatter foam of the right density — either a replacement seat or your own pan re-foamed and re-covered.

  Numbness at 90 minutes is the most common reason a touring day ends early, and it is a foam-density problem, not a padding-thickness problem. Re-foaming your own pan also lets you take height out for a shorter inseam, or add it for a taller one.

  Check before you order

  • — Seat height change in both directions — say which way you want it
  • — Off-road: a flat seat you can move around on beats a plush bucket that pins you in place
  • — Heated seat elements need a switched, fused circuit

• Top box on a plate

  Luggage & load carrying$200–$700 · ~1 h to fit

  A lockable 30–50 litre case on a mounting plate over a subframe-mounted rack.

  Where a helmet and a shop run live, and the only luggage most commuters need.

  Trade-off: Raises the centre of gravity at the worst possible point.

  Check before you order

  • — Rack load rating including the case's own weight
  • — A big box far back is the classic cause of high-speed weave — keep the load light

  Search for parts:Amazon

• Taller gearing for cruising

  Fuel range$70–$220 · ~2 h to fit

  One or two teeth more on the countershaft sprocket, or fewer on the rear, with a chain to match.

  Drops highway revs on a bike geared for the trail, which is worth real fuel economy, less vibration and a longer engine life on a big single.

  Trade-off: Loses low-speed tractability and clutch life in technical riding.

  Check before you order

  • — Chain length and adjuster range — a bigger front sprocket may need a longer chain
  • — Clearance between a bigger countershaft sprocket and the case or chain guide
  • — Speedometer error where the sensor reads the front sprocket or gearbox

  Search for parts:Amazon

• LED headlight bulb or unit

  Lighting & visibility$80–$400 · ~1 h to fit

  A quality LED retrofit in the stock reflector, or a complete LED projector unit.

  Older halogen units are the reason night riding feels like guessing. Done properly, this doubles usable light without touching the charging system.

  Check before you order

  • — Reflector geometry: a cheap LED in a halogen reflector scatters light and blinds oncoming traffic
  • — Beam pattern must keep a legal cut-off in your market
  • — Some bikes need a decoder to stop a bulb-out warning or flicker

  Search for parts:Amazon

• Better battery, or lithium

  Electrics & charging$100–$450 · ~1 h to fit

  A quality AGM in the stock size, or a lithium-iron pack where weight matters, plus a matching charger.

  Most no-start faults are a tired battery, and a lithium pack saves 2–4 kg on a dirt bike. AGM is the better answer for anything that sits in the cold.

  Check before you order

  • — Lithium needs a compatible charger and dislikes cold cranking — a bad choice for a winter commuter
  • — Case size and terminal orientation in the stock tray, and vibration padding
  • — Whether the bike's regulator is kind to lithium chemistry

  Search for parts:Amazon

• Quality chain and sprocket set

  Reliability & longevity$150–$400 · ~3 h to fit

  An X- or Z-ring chain and a steel rear sprocket, replaced as a set with the front.

  A worn chain destroys new sprockets in a weekend, and a chain that snaps at speed can take the cases or the rear wheel with it. Steel rear sprockets last several times as long as alloy ones off-road.

  Check before you order

  • — Pitch and link count from the manual, and whether a rivet or clip link is acceptable
  • — Gearing change while you are at it — decide before you order

  Search for parts:Amazon

• ECU flash or fuel controller

  Power & fuelling$200–$800 · ~2 h to fit

  A remapped ECU, or an inline fuel controller and an O2 eliminator where flashing is not available.

  Most modern bikes are lean and abrupt at small throttle openings to pass emissions tests. Fixing the fuelling removes the snatch and the surging — a bigger real-world gain than peak power.

  Trade-off: Voids the powertrain warranty on most bikes and can fail an emissions inspection.

  Check before you order

  • — Whether your ECU can be flashed at all, or only piggybacked
  • — Emissions legality and warranty in your market
  • — A map matched to your exhaust and filter, not a generic file

  Search for parts:Amazon

• Exhaust plus matching fuelling

  Power & fuelling$300–$1.4k · ~3 h to fit

  A slip-on or full system, fitted together with the fuelling change it requires.

  The honest reasons are weight — a full system can save 5 kg high on the bike — and a cracked or rotten original. Power is a side effect and rarely the biggest one.

  Trade-off: Noise, legality, warranty and resale, and a full system on a modern bike often needs an O2 workaround.

  Check before you order

  • — Noise limits and homologation stamps where you ride, and at track days
  • — A slip-on without a fuelling change usually makes a lean bike leaner
  • — Pannier and crash-bar clearance around a bigger can

  Do first: ECU flash or fuel controller
