This rocket has an HMF after market pipe on it, I still have the original pipe and assembly also. I mounted a fender eliminator on this beautiful bike, It has had its first service done at 600 miles. Right now the odo is right below 1400 miles. This bike looks great, Performs awesome, and is practically brand new. Not a scratch on it. I live in Alaska most of the year and really dont have time to ride anymore. The EBR is chain drive and sits on Perrelli tires.
