These modifications were very affordable and the installation process straightforward.

Increasing the KLXs engine size from 110 to 150ccs brought about a huge increase in power. Unfortunately along with more power comes more heat. At $385 the Moto HP oil cooler kit may not be the cheapest kit on the market but it is a quality product that has been specifically designed for our bike.

We'd heard about those Baja bikes hitting 115 mph or more, while some experts have flatly stated that no production motocross dirt bike will run over a hundred per. Even with the tallest possible gearing to be had. Well sir, the arrival of a 495 KTM and a genuine maniac Six Days rider appeared to us to be the perfect combination.
