My 250 Monza project bike, the before pic.
The vision of what "after" should be has changed a few times, but now I think I'm pretty much set. I've got some flanged alloy rims for it, 35mm Marzocchi forks, an abused Mach 1 style tank, and it seems a 350 Sebring engine has also found it's way to my shop. I was torn between going with a disk or drum up front, but F05 calipers don't grow on trees and in the mean time I stumbled across a front hub so put this together.
And that's about as far as I've gotten. The 160 and the hardtail need to be finished first though so this thread will likely sit for a while before there are any updates... more info should be here too: http://www.teamyikes.com/bitsahome.html
Regarding the brake... I also have a 125 Sport gas tank awaiting a bike. I'm now thinking I might continue looking for a disk brake set up for the 350 Bitsa, and find another donor to build a 250 Phantom Sport from, and use this brake on that...
