KX636 Trophy Bike

My buddy and I have been working on this build for over two years now, in between work and other projects, but we are nearing completion and wanted to share the progress we've made! The goal was to make a very strong frame with a streetbike motor in it, so the bike can do more than just climb hills (we race and promote Pro motoclimb races). Essentially the trophy truck of dirt bikes. We want it to be a reliable rider, because nothing is more fun than taking a 100HP four cylinder bike on trail rides!

Everything on the bike is KX450/250 parts, except for the motor, electrical, and main frame. We built the frame out of 1.25x.090" DOM tubing, and everything is fully TIG welded. The geometry is nearly identical to the stock 2013 KX450, which will be interesting to feel once we start riding it. That tight geometry with such a large motor makes the build extra difficult, and we are very tight on room. The motor is from a 2005 Kawasaki ZX636.

It's a work in progress but it'll be a ton of fun when finished!
