Do not assume it fits a bike or engine that is not named here; ask the store first. - [Japanese Mini Bike Parts > KLX 140 > KLX140 Engine and Carb](https://tboltusa.com/store/klx-140-klx140-engine-and-carb-c-100_602_1142.md) Where a fitment line says "All", it means all years of the model named on that line, not all bikes. ## Description (the store's own text) Upgrade your clutch and change your oil and filter all at one time with this kit! TBparts HD clutch plate kit for the Kawasaki KLX140. This kit was designed to hold more power from the ground up! We did away with the OEM “jitter” fiber & steel. This firms the clutch up and gives you more frictional surface to grab! Next we upgraded the OEM cork and rubber fibers to Kevlar for improved grabbing power. To go with that we used dimpled steel plates for the additional friction. Finally, the springs are 15% heavier than factory. Enough to hold big power with the other upgrades, but not too stiff where it makes the clutch pull harsh. All that for $36.99! You can use these as factory replacements too! **Key Features:** - Deletes the OEM Jitter fiber and steel plate - Kevlar Fibers - Dimpled steel plates - 15% over clutch springs **Includes:** - TBW1597 - TBparts HD Kevlar Clutch with HD springs - TBW1667 - Clutch cover gasket - W-78-9880 - Maxima 10W 40 engine oil - W-550-0112 - Oil filter **Application:** - KLX140 **Note:** Installation note – This kit replaces the OEM Jitter fiber, spring, and steel plate with a full sized fiber and steel. ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
