Trail Tech Ignition Map Switch With Kill Switch Trail Tech Ignition Map Switch With Kill Switch Trailracer - Reno. Nv Worthy product "Purchased the three level ignition map switch for my2014 ktm350 SXF. The instruction were clear and it only took a hour or to install. The bike fired right up and switch worked great. They could have made a mark on the middle setting so when riding it would easier to see that you have moved to mild sitting while on the fly. But you could do that your self with a marker. If you trail ride terrain that has wide variety or like ajustments , this switch is a good choice."

Is your clutch slipping or dragging?

A dirt bike clutch can take a lot of abuse. A tiny strips of friction material and a few steel plates is all that holds the power of your bike, transferring it to your gearbox and on to your rear wheel. If they become worn or, worst case scenario, the friction pads separate, you'll need a new clutch. Generally, a new clutch will last quite a while even on race bikes, due to new materials being introduced like kevlar and carbon fiber. The Barnett Clutch Kit With Carbon Fiber Friction Plates is one of those, using carbon plates for longer life and better heat resistance. If you want the best of the best, check out the Rekluse Core EXP 2.0 Clutch Kit, which works by incorporating sliding wedges into an expanding friction disk. Wedges provid increased clutch performance at low to mid RPMs over traditional ball-bearing auto-clutches. They also offer a 30-day money back guarantee if it's not for you!
