Fast50s Speed Exhaust for the Honda xr/crf 50 Stainless for durabilty and shine. It weighs in at just a fraction of stock. Our pipe runs similar on the bottom end, but then takes off with a incredable mid range punch (which is really what the 50 needs). It also has a bit more top as well. This is "THE PIPE" for you to get the power gains you need and paid for. Works great on stock 50cc's all the way to over 88cc. We even run this on our 106cc bikes for tight tracks. Also available in 1" for 95cc to 124cc bikes. (We have even run this o REALLY ripping 88cc motors hat want more top end power.) Made in America. FREE SHIPPING TO UK & MAINLANDS!!
