Had randy build both bikes for me (450 & 250). The guy ABSOLUTELY knows his stuff and the quality is top notch. Both bikes are rockets that I have a hard time holding on to on the track. Will not let anyone else touch my bikes ever again.

Randy at FastMann is one of the best on the east coast. Pays attention to detail. Machine work is top notch. Takes on things others won’t.

Michael K.

Excellent service and owner/operator. If you ask me, he is the best in the business and no other shop compares to the level of the quality work that he does. It might have taken a little longer than some of your bigger shops like twiggs to have my bike rebuilt, but it was done the CORRECT way. Excellent prices and everything I was looking for. I highly recommend this place and I will be returning!

He is the only man that I will allow to touch my bike. Randy is the man you need to see to take your street or race machine to the next level. He is a wise wizard with quality parts, tools, expert machining capabilities and a dyno. What more could you ask for?
