What you’re feeling on the motorcycles is an effect of tuning, not configuration. There are some 4 bikes that make low end torque (look at the Bandit and some singles that all their torque at high rpm at any motorcross bike).

If you grab a few dyno plots, see that displacement makes and the state of tune of the engine the RPM that torque happens at. The of torque is dependant on the engine For a given displacement that is. valve is the lowest, over valve is better, four are better than that. cooling too.

Air cooling is the oil cooling is better, water is better than that.

Ive a Yamaha XJR1300, loads of but nothing compared to the Honda XR 500 4 CR 500 2 … and Kawasaki KX 500 below RPM snap.

i loved coming around a dirt hairpin turn to home in 3rd on my XR, the engine bucking to stall at below idle rpm and cracking a umph of throttle and the end would sweep out gracefully an almost full lock The CR was even more potent but go down to way below idle load without bucking the 4 ….

the KX was angry. I saw it in a shop in NW The salesman said a guy bought it for his son and it back after 4 rides it will kill his son.

Because I rode it on the streets in I put the largest front sprocket and back sprocket available. I put multiple cylinder base about 3 millimeters thick to the compression and machined a weight for the mounted ignition rotor, in an to tame it down

i used to it on a gravel road, click it up to 5), bring up the rpm to between 1/3 and 1/2 and dump the She would spin the rear and the rear side to side accelerating from a standstill.

at just about 20 mph in top gear, I push down on the front end to the forks and on the rebound wack the wide open pull up on the and throw my weight back and she almost effortlessly rotate up to 11 That’s not far above idle without using the clutch.

The BSA 441 shooting star I owned did not like the dirt bikes probably because she had a heavy She would pull very low bucking like the XR. I remember slowly in a narrow slippery footpath and was surprised how she would so spin the rear wheel I eased out the clutch to move out at a pace.

And that is with max finesse the clutch and throttle, but the torque at over combined with the flywheel was almost unstoppable.

as grunty as the 1300 is there is no in the below idle snap of big singles I rode. I don’t they make bikes that anymore probably those with smoother, torquey power deliveries much better lap times.

coupling the cranks of 2 KX 500s, or any of for that matter, and firing jugs together would a serious torque monster,
