Most radical GP bikes?

I suppose only bike that have actually raced should be admitted...

The Hondas 250 and 297cc 6-cylinders definitely belongs there.

I found an incredible disassemble video of the 6 cyl. on YT:

And then the incredible 50cc's of the '60s!

Honda twin 4 stroke dohc 8 valves 50:



Suzuki 3-cylinders 2-stroke 50:

And Taveri's 125 cc 5-cylinders 20 valves dohc...

A good view of the Guzzi V8:

The mother of all modern IL4s, the Gilera 4 cyl 500cc:

And the MV six:

Top stuff, J4

No, that actually was King Kenny punching you in the face.

The black Norton which Ron Haslam raced in the 1991 British Grand Prix.

For you to know this, you've either been donkey-punched by a female with a strap-on or by Willski...actually, logic dictates that it's both

Epic post Dr No!

The Britten bike was something I drooled over, the pictures do it no justice.

I can remember someone once saying that the Honda NR500 was terrible, if you broke too hard you'd change ...

The article seems to be inaccurate. It says, for the original KRV5, "The engine was ditched and replaced with a V4 KTM motor, with no improvement in results."

That never happened as far as I recall, only that it was talked about.

A lot of personal favorites have been mentioned, but I'd also like to show this even though it was not a GP bike nor a Superbike,

The Norton NRV 588

In 2005, the time had come: The KR team finally started a MotoGP with me on board. Kenny Roberts and KTM had agreed to join forces. Briton Shane Byrne was engaged as a rider. KTM provided the engines, bore the cost of the rider’s salary and paid for the Michelin tyres. With the help of external sponsors, the Roberts team was responsible for ensuring sufficient funding to cover the running costs.

But the collaboration proved ill-fated, bringing only moderate success. I would have preferred sophisticated electronics from TAG McLaren or Magneti Marelli, but I had to make do with a cheaper EFI system from England. This impaired my rideability, which ultimately affected our performance. My best result with Shane Byrne on board was 15th place at the Laguna Seca GP, which earned one Word Championship point. At a rainy Donington, a podium place was within reach for much of the race, but our hopes eventually ended in the gravel trap. My last MotoGP appearance then came to an end with an early crash at the Sachsenring circuit.

When there was no end in sight to the discussions about team financing, my bosses eventually drew a radical line under the matter. At the Brno GP, the KTM engines were collected and taken to Austria, which represented the end of the GP1 and MotoGP story for me as a power unit.
