I'll have to do some calling around and see if I can locate the right bike and collector. I am sure they are out there, and would much enjoy taking a Hummer for a spin. Those bikes are an interesting point in the Harley Davidson story.
As an "older" ex road racer and Suzuki dealer, I can't leave the bikes alone. But even in the younger crowd, the Groms, Monkeys and repurposed CT70's (with 190 or 212cc engines) are extremely popular and a blast to ride. Lot's of modding going on in this segment. One problem for the bike manufacturers is simply price. The younger crowd just can't afford bigger new bikes that cost as much as their daily driver cars. But, even I find myself walking past my CB750F and VFR750F to the CT70 with 12in wheels, extended swingarm and 190cc kit. The little bikes are just fun in a childish sort of way. If Honda made a 250 Grom and Monkey, they would be the perfect urban/suburban run-around bikes and they are not intimidating- light and super easy to ride.
Want to review vintage bikes? There is a lot of vintage iron in Greenville SC. I have a 64 Triumph Tiger (just like the one Bob Dylan rode) 99 point bike AMCA. 68 Bonneville, w springer front end... British racing green, it's the 'dangerous bike' but oh so cool, classic 74 Honda CB750, 2010 Concours. I have a friend down the street with a big collection of mint condition crotch rockets from the 90's, all stock, all beautiful, tons of material to write about in one garage. Also buddy near by, expert in vintage British bikes with a shop, Norton, BSA, Triumph what ever you want. Let me know if you're interested to drop by. Dave S. LakeDave
