Ok, it's not a speedmaster or america, sorry. My bike is apart now being 904'd and I decided to get an SV650 front end and wheels because:
1. I needed new tires, chain, brakes, and sprockets anyway
2. 17'' sport bike black mag wheels look cool
3. triple discs rule
4. spokes break, inner tubes suck
2 friends of mine own SV650s so I measured everything and it was all pretty close to the bonneville as far as fork length including to the bottom of the tire so rake/trail won't be changed. It will be nice to have the Zrated sport bike rubber and 2 floating discs up front.
Here's a photoshopped version of what it will look like:
I'm going to get the motor back together and broken in before taking the front end off, but it should be done in the next 2 months. I want to call it a Speed Twin, and maybe get some carbon fiber parts like front fender, maybe side covers, etc.
