GAS GAS
Trials DNA, sharpened for motocross and hard enduro. The character is playful up top, savage in the midrange, and the chassis rewards a rider who commits. Landings load the wheels hard. Bearings take a beating. Hubs need truing. Stock the workshop accordingly. Pick your model from the rail or filter the parts below.

Refine your fitment →GAS GAS parts — frequently asked questions
Common questions, straight answers. No fluff.
- Some yes, most no. Bars, levers, grips and brake pads cross between the trials and enduro lines on shared mounting hardware. Engine internals, swingarms, shock linkages and bodywork do not. Confirm the model designation against the part page before you order.
- Pull the VIN and cross-reference the model year on the head-stock plate, not the badge on the tank. The platform refreshes brought new subframe mounts, revised airbox shapes and different stator covers within the same model name. Plastics and levers often span three or four years on one tooling cycle. Pistons, cylinder heads, clutch baskets and shock springs rarely do. Every product page lists the year range it covers. If your build year falls on a cusp, match by part number off the OEM fiche before you click buy.
- Run the hour meter, not the calendar. A hard-ridden 250 two-stroke wants a piston, rings, small-end bearing and fresh base gasket every 25 to 40 hours. The 300 stretches further, 40 to 60. Measure bore wear with a bore gauge before you pick the piston — A, B or C size depends on the cylinder, not the box on the shelf. Replace the power-valve governor spring on the same job. Skip the measurement and you'll either seize a fresh top-end or eat the plating inside an hour.
- Valves and cam chain. Shim the clearances every 15 hours and log the numbers — when a bucket drops out of spec twice in a row, the seat is receding and the head wants a refresh. Cam chains stretch silently until the tensioner runs out of travel.
- Stock gearing on the enduro models suits trail and woods. Drop one tooth on the countershaft or add two on the rear for tight single-track and steep climbs. Motocross riders running fast, open tracks usually go the other way. The chain slider on the swingarm wears through in a season of mud riding — check it when you change sprockets, because a worn slider eats the swingarm aluminium underneath.
- Fork seals and dust seals in the right stanchion diameter, a litre of the correct-weight fork oil, and a shock seal head kit. Linkage and swingarm pivot bearings take water through the dust seals every wash — pack them or replace them annually.
