1995 KTM 300EXC Dirt Bike Torque Specs
Shop parts for a 1995 KTM 300EXC Dirt Bike.
The 1995 KTM 300EXC introduced a significant update in the form of a new WP upside-down fork — replacing the conventional right-side-up fork that had been standard on the model — which dramatically improved front-end feel and tracking precision on rough terrain. The new fork also changed the front axle fastener configuration, requiring attention when torquing front axle hardware on 1995 compared to earlier models. The engine continued to evolve with refined porting and power valve calibration for improved tractability. The 1995 model is a notable transition year in the 300EXC lineage and is well regarded among vintage enduro enthusiasts.

1995 USD Fork Notes
The 1995 introduction of WP upside-down forks changed the front axle clamp procedure compared to earlier 300EXC models. After inserting the front axle and torquing the axle nut to 20–25 Nm, apply the front brake firmly and compress the fork several times to allow the lower leg and axle to self-align before torquing the pinch bolts on the USD lower legs. This procedure is critical for correct fork tracking and is specific to the USD design.
