You will however be amazed how slow they are in stock form. With the 80cc kits they are pretty quick though...kit can't be very expensive I don't think.

Pretty quick would be about 1:50 flat at NHIS. A good rider can sometimes beat Mary on her 50. Ruffo has beat her a couple times on his Derbi with the kit in it.
