I'm building a project bike instead of just buying a scooter to fill the need for in town transportation. At most I'll use it on the freeway (75mph) for 18 miles a few days a week which is why I need a little more than the average scooter will deliver. I want a 125-250cc 2-stroke engine with a wide ratio 5 or 6 speed transmission. I'm figuring a single cylinder engine so I don't have to deal with 2 expansion chambers. The bike will have a Ducati steel trellis style frame built by me, a '94 Honda RS125 front end, fuel tank and 17" wheels. In general I'm looking for recommendations like "hey, you should try to find a 200cc banshee engine" etc. I'm going for a little something like this: Side note; the Yamaha SDR200 fits my bill of needs perfectly so if you know anyone who has a basket case, I'd love to know about it.
