Dirt:
A lighter weight bike is safer and less tiring and faster; totally ! : My slightly modified Suzuki TS185 Sierra was a very competitive ride in comparison to the stock TS250 Savage.
Myself, on enduro more like 50-50 braking and on my Montesa VA360 motocrosser, barely used the brakes, it was slide forward, engine brake, pitch her into a corner and then woo-hoo! accelerate out of the corner on the rear wheel The front wheel seldom touched the ground except coming into corners, …maybe I was just riding way faster Long cushy seat and long travel suspension. Tall most definitely, VA360 had 13 inches of ground clearance even with a big down pipe.
Trials mmmmm Trials, full body exercise machine ! Back up to 80% front brake, rear brake can be almost completely replaced with engine braking, …have even taken trophies after completely loosing my rear brake early in the event. First 3 gears are used mostly, rarely 4th. rumor has it there is a 5th. gear. Engine: low and mid range tractability, low center of gravity and the lightest motorcycle known to man. Seat is a sticker, but the fender is very comfortable, even though your knees are up in the air when you sit down. Fuel if you forget to bring any, you can borrow from me, they barely use the stuff.
Street:
Agree with your comments, the biggest rush is to go fast, ( and go ahead and flame me for saying it …kinda boring once you ride Trials.
Roadracer and Sidecar Racing: In a league of it’s own, I love the small displacement roadracers and would totally love to try (classic) sidecar racing.
