My snowblower-powered CVT roadster. I had a bunch of extra parts on the workshop shelves, so I decided to put them together. The engine is a 6-1/2 HP Honda GX200 clone. It is nowhere near finished, but as of this morning, it's at least rideable.
- 1974 Panther Black Shadow DB175 frame
- LCT 208cc engine, as used in Husqvarna snowblowers with CVT torque converter
- 1976 Yamaha YZ125C swingarm
- 1989 Honda VTR250 Interceptor inboard disc front wheel
- 1982 Suzuki GS650GL front forks
- 1985 Yamaha XJ700 Maxim front fender
- 1977 Can-Am Qualifier fuel tank
- 1995 Kawasaki EX500 rear wheel
- Suzuki 500 Vinson ATV rear caliper
- Honda CRF150 rear sprocket
- Honda ATC90 foot pegs
I am happy to report that having now put some miles on The Bride of Frankenstein, it’s a win in my book.
The overall riding experience is peculiar, but easy and fun. Think of it as a Honda Navi with bigger wheels and better brakes.
I paid a lot of attention to the steering geometry early on, and despite the odd look of the trailing-axle fork, it works. The steering is easy and predictable—neither truckish nor squirrelly. The suspension is better than those bargain-basement damper units would suggest. The engine starts from cold with just a moment of choke, idles nicely, and pulls through the rev range without hesitation. It took a few miles to remember that the rear brake is on the left handlebar instead of under my right foot.
There are few niggles. The $35 seat feels exactly as comfortable as you’d expect from a $35 seat. The super-wide, non-folding ATC footpegs aren’t optimal. Their width not only complicates getting the bike in and out of the garage, but they also vibrate a bit on the road. Surprisingly, I didn’t feel much vibration through rest of the bike and the mirrors stayed clear.
The engine got an aftermarket crankshaft, ARC billet rod, and Tillitson flat-top piston. It has full electrical system, with 60-watt alternator, an electric starter, and full street lighting.
My design goal for this bike was 50+ MPH, and it is just able to meet that top speed. However, acceleration requires an eye on the tach. Whack open the throttle with abandon and the ungoverned engine can exceed 4000 RPM before the CVT’s gearing can catch up. The tach’s “max” memory function currently reads 4310 RPM—not alarming, but definitely approaching iffy territory for a cast flywheel. A little bit slower roll-on is all it takes to keep things in a safer range.
Given the motley collection of components I started with, I’m thoroughly tickled with the result. I love the uniqueness of it. Even I would have never conceived of this machine, if not for the collection of parts I had to work with. I knew it would be a novel curiosity and a rewarding project. But it’s actually a genuinely usable, thoroughly street-worthy means of transportation, which I wasn’t too sure I could pull off.
So, with that, I am calling this project complete. The bike works as well and looks as good as it probably ever will. So here a couple official glamour shots.
