…I would so love to get you on the back of my K bike. …not to scare you, just to enlighten.
Sounds like a tall order to find appropriate videos but i’ll give it a shot later, ANY size bike can get out of hand real fast, I have a friend that just started riding a Kawasaki 250 ( big tall strong guy ) within the first week riding he pulled an uncontrolled wheelie while entering the roadway from an inclined driveway, the bike was T-boned by an SUV. Fortunately he was no longer on-board at impact but the bike was creamed. …sorry no video:(
The big differences are once you get out of shape, a lighter bike is easier to regain control over. An extremely powerful bike can literally pull out of your hands and a ‘pipey’ bike ( one that has a narrow power band that comes on all at once somewhere in higher revs ) can loft the front wheel at very high speed. I once test rode a 70’s model, modified Yamaha RD350 that was mild mannered at normal road speed but if you twisted the throttle and waited for it to hit 5500 rpm, the thing would cat walk from about 40 mph. and it was even fitted with flat bars. It was not a pleasurable bike to ride, way too much like throwing the switch on a big bottle of Nitrous Oxide. Scared the crap out of me and at that time I had 8 years experience.
Almost time to start tapping the Maple trees
