1976 Suzuki TS185


This is my first custom bike build. No plans or drawings were done for this build. I started with a $250 basket case TS185 found on market place and only a rough idea in mind. I stripped it down to a bare frame, put it on the bench and let the bike develop organically from there. I basically just designed and fabricated as I went along, just doing what I though looked right.
Even with the extended swing arm the wheelbase is close to stock due to the steepened head tube angle. As a result the steering is more responsive and the weight of the bike is now more centralized and with the low ride height it feels like riding a BMX with an engine.
I didn’t use any software when designing and building the pipe. I just welded a bunch of cones together into a shape that I thought looked like it would work. It made a big increase in power in the mid-high rpm range and it sounds like a 125cc Motocross bike.
It wasn’t originally going to be finished in this color scheme. When I dropped the frame off at powder coat I asked for it to be royal blue.
When I went to pick it up I saw it had been done in purple instead.
Rather than get them to re-coat it, I decided to base the rest of the paint and graphics theme around the purple frame. That’s why I used the white base with pink and purple graphics.
This bike isn’t going to be liked by everyone. I am totally fine with that. I wanted to build this bike 100% for myself. If other people like it too, that’s cool, but if they don’t that’s cool too.
