How powerful is a ZXR race machine with 70+ Bhp VS a 2 stroke machine with the same Bhp.

For example NSR Honda/Aprilia RS/Suzuki RGV etc.

I read the rules for F400 and limit 78Bhp for the 2 stroke.

Plus the minimum weights

2T 250cc 122Kgs

4T 400cc 145Kgs , this is not fair.....

For the fuel the rules said...

4T road-gas , 2T AVGAS....

Race guys are welcome.

A video from the past. Carl Fogarty vs James Whitham (here the V4 machine how many Bhp is ???)

i have spent ages thinking about getting a 2 stroke,rgv,nsr or something like that,in the future ,sometime.
but say if i get one il just be doing stuff to it to make it lighter /faster etc.
i might aswell just get a tz 250 and be done with it.

i picked up a full f3 spec rgv imported from japan, it was the absolute billy's even back in 95 it was kicking 73bhp and felt oh so much faster than than a tuned 400 but in reality the 4's are easier to ride making lap times comparable, but if you ever get the chance to stick a leg over a full on race 2 stroke

the gp 250s are meant to be some buzz!
they weigh like110 kg ithink,85 hp,
was talkin to a lad who had one for 3 years ,he said the engine was bullit proof,
he did have to do piston and rings,but notin else major.

Can race in UK TZ and RS machines VS ZXR 400?

Here in Greece, we have 250 GP category alone.

In SS400 only 250 production and 400 production.
