Serious question. Why ride a motorbike so fast, without being able to hear approaching traffic due to the loud noise coming from the engine.

I suppose they use the loud noise of the engine to alert other vehicles of their presence. The same way as emergency services vehicles use sirens and flashing lights.🤔

No they don't. Thats how a lot of them are built. If a car driver cannot see a motorbike. They should not be on the road. Your car engine would be quite loud if it was not fastened in a box.

If you are driving “so fast” the only approaching traffic will be oncoming or from side roads.

I'm thinking more of motorists, etc who can't see an approaching motorbike due to them having their view restricted by buildings, trees, high sided wagons etc. Not those who could see the motorbike, but choose not to!

A very cogent point Accy, equally applicable to any other legal roaduser, those that can see ,but choose not to.
None so blind. That the cannot see.

Whilst riding a motorbike at any speed it is mostly wind noise that you hear, and it is loud enough to be a hazard such that wearing earplugs is very strongly advisable. Even with offensively loud exhausts I doubt the rider would hear much of the engine whilst underway however annoying to anyone else.

I should stress I just had the factory pipes on mine albeit it was likely louder than a car because the engine was less enclosed, but still, it's wind noise you hear whilst riding along

The olde FJ1200 was the first bike to failmUK government noises tests because opening it hard from a roll-on in second caused it to wheelspjn past the microphone. Manufacturers dodge this by designing the torque curve to get them through the test without any undue grief.

Yep my mate had one and it was incredible, bought from Chris Vincent's shop in Earl Shilton it was one of Chris' personal bikes and had been 'got at' slightly (gas flowed and the airbox restrictors cut away)
