Crispy Fried Yamaha DT175's

The Motard / Supermoto concept is simply the ubiquitous Yamaha DT175 with early 80s Suzuki RG250 Gamma front end and rear wheel. Both share the same rear axle sizes. I think its way cool and would be a lotta fun! Its funny, the smaller the bike the more fun it is!
The late 70s to early 80s road racer concept is also Yamaha DT175 with early 80s Suzuki RG250 Gamma front end and rear wheel and TZ250/350 seat and tank. The tank will need to be shorter to suit the DT. This is my favorite concept since coming up with the DR400 vintage supermoto!
I would like to do this project in this order - first building the Supermoto and then later the micro-road-racer.
