Jim Mickle's Yamaha YFZ450R ATV

Quad of the Month - September 2011

Jim Mickle's Yamaha YFZ450R ATV

"I bought this bike new from Stadium Yamaha in Irving Texas August of 2009 with the intentions of not modifying it. Well that didn’t work and the disease took over.

I ended up with just a pipe and a programmer at first but that just wasn’t getting it done. So I contacted Geoff Mummert with Mummert Machine and Development (MMAD) out of El Cajon California. For the engine work.

I’d like to thank David and Jason with Quadforce, Garrett with Fuel Customs, Dave Herron with JD Performance, and Stadium Yamaha for all the great go fast parts."
