Tank Slap - Motorcycle Forum

Iirc my SuperDuke GT was quoted as 106lb:ft and at least 100kg heavier, it was no slouch.

I can't imagine what this thing will be like to ride, somewhere between insanity and wonderful madness?

It’s a rotary it will fall to bits

It's the curve more specifically. It will ride like a supercharged 600 would, not like a torque monster such as the 1290R KTM.

You aren't going to be at 5000 rpm, twist the throttle and have the bike catapult you down the road, you'll need to be at 12 for that to happen. It SHOULD have the most easy to use curves on the market.

It would be totally wasted on me, there's no way I could ride that thing, amazing as it is. It's a proper race bike for actual racers.

Interesting that they have chosen a single rear shock, mounted in the ( largely abandoned ) traditional location.
I imagine the savings realised from that simple approach may have contributed to the very low weight.?

I think they had to do that as the silencer for the exhaust is where it would be if it were mounted in the centre .

I think you could both be right. Lightweight bikes require less complex suspension systems now suspension technology is so advanced and it also meant they could route it how they do.

I dont think it will ride anything like a supercharged bike, I have driven a few highly tuned rotary engine cars and they make all of the power at high revs then explode in a pile of bits
I have a tuned R53 with a geared down supercharger and it makes all its power low down, such a perfect B road car

To be more specific I'm talking about a root supercharger where, from a few hundred revs above idle, it acts as a multiplier on the preexisting power and torque therefore increasing gradient but otherwise leaving the curves alone. None of this Kawasaki "centrifugal supercharger / turbo halfway house" nonsense which only really adds power to the top.

Is 105 lb - ft low torque ? From a 690cc motor ?
The Ducati V4S is only 91 lb - ft from 1000cc

fwiw I think it'd be a real beast to ride but enormous fun and very satisfying when you got things right but very painful and expensive if you got things wrong .

True, but it is not 690cc in the conventional way of thinking. Very hard to compare the volume of a Wankel engine with a traditional four stroke engine.

I hadn't even thought about that. It's often a 1/3rd the equivalent volume of an ICE engine if the marketing blurb from a couple decades ago can be believed.
