Don't kill yourself COLOMBO. People love to die on those fucking things. I saw a kid die in front of my house the other day. Laying lifeless on the pavement. It was rough.
Sick bro! I used to ride a 2003 636. Dont listen to anyone who says you should got something bigger. Unless your are a fucking pro rider you will never be able to use a 600 to its full potential. Gear the fuck up whatever you do. I seen so many people crash road racing up berryessa its not funny.
