## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [TB Parts > KLX140](https://tboltusa.com/store/tb-parts-klx140-c-68_1113.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)

Easy bolt on power for your Kawasaki KLX140! This TBparts high performance camshaft is for use with either the stock bore or our 63mm/170cc big bore kit. You will not find a better cam for the price! Starting around 5,000 RPM this cam starts making significantly more power than the OEM cam and carries it all the way to the top end allowing you to rev out farther and make more power! As with all our cams, the quality is also exceptional and not a regrind OEM cam.

**Key Features:**

- Well over 1hp gain in stock applications
- Brand new camshaft and bearings
- Works great with the stock cylinder head on a stock or modified KLX140

**Application:**

- KLX140 - All years
- KLX140L - All years
- KLX140G - All years

**INSTALLATION Note:** KLX140 camshaft bolts are reverse threaded, turn them right/clockwise to loosen/remove.
