I think I made a big mistake buying this bike 1st I had no idea the engine was assembled in China. Buying Chinese anything is like a sin to me nothing but junk is made their 2nd I cannot find a performance exhaust anywhere and it doesn't seem any and I mean anyone ever made any I've tried Supertrapp, Yoshimura, Two Brother and others nothing. I beleive I made a big mistake buying it although it only ha 6700 miles on it and it looks brand new
