Fast, clean bike never wrecked. Has fmf fatty into a fmf shorty exhaust. Bike tops out between 70 and 80 mph. Bike has never fouled a spark plug, I am the second owner and the man I bought it from gave me an extra spark plug for it, but I have had the bike over a year and have never once had it foul a plug on the trails. I am selling because it is a racing bike and I spend most of my time on trails.
