Here's what happened to a friends Streetmate after the front brakes failed and he hit a pole. We repaired it, first by trying to use the Magnum triple trees and stock forks... Not happening. Then I told him fuck it, just use the whole front end off the Magnum. You can see how that came out. He couldn't put the forks on being too drunk and angry so he went off to cut his thumb open by breaking bottles against the garage. My friend who owns the garage built it overnight.
I think the bike is 100% better, both the front and rear drums work great and the seating position is awesome. I hated the way the bike looked stock, it was way too girly. It used to be slow as shit too, topping out at 30 flat but now it feels like its going 40 maybe. Remember the bike isn't modded motor-wise, just the frame.
