Panterra Cafe/Street conversion

[alex_in_az]

I love the Panterra, but I don't ever take it off road and the knobby tires don't let me get the best out of it on the street. so I decided to do a street conversion to it. I got a seat, tank, pipe, pegs and side panels from Taobao.
I started by looking for replacement tires, but the 21" wheel was hard to find tires for plus it just didn't look right. So I found a replacement front wheel at a local wreckers from a 1975 CB200t. This had a smaller disc brake than the Panterra with an incompatible bolt pattern. I re-drilled the bolt pattern and turned a spacer to get the correct offset for the disc.
The new front wheel lowered the front end, but it wasn't where I wanted it, so I replaced the handlebars with clip ons and allowed the forks to protrude thru the triple tree to mount them, this further reduced the front end height and gave me the look I wanted.
The rear needed to be lowered as well, initially I was going to reduce the number of coils in the mono-shock, but after running a few spring calcs I decided the best thing to do was to leave it alone and modify the frame instead.
The tank mounts were similar, but in the wrong place. So I lowered the front ones and raised the rear to compensate for the change in tank shape and lowered rear frame.
