i didn't say at the wheels, and top indicated speed is actually 180, and mines been up to 175 (although not by me) and the speedo is probably inacurate at that high a speed, it's 33 hp at the rear wheel

I would agree with you there.

The VT250Fs are not that slow and the later VTR's were quite detuned apparently, as well as losing a cog in the 'box.

But the GT250R's are definitely a great looking machine.

Yeah agree there, had an 87 model and I'm pretty sure that was down on a bit of power (smoked a fair amount) but still went pretty well. Awesome bike to learn on, cheap to crash too. Crap front brakes though, stupid inboard rotor system.

P.S. Wasn't aiming my other comment at you mate, just putting the guy I quoted straight.

don't want to start a fight here, but what do you mean putting me straight? you were the one that assumed i meant at the wheels, as i said above it's 33hp at the wheels, 45hp at the crank, i have done my research on this bike, oh but the one thing i haven't found out, is how to fix the dodgy fuel pump in these, before it breaks and causes the engine to eat itself, anyone know? (sorry about the thread hijack but at least we're still talking about v twins

)

Nah sorry mate, no way the engine makes 45hp anywhere (maybe if you hooked it up to nos). I'd say its 35hp at the crank, 33 wheel. Normally the losses from crank to wheel are around 5% so that would be 2 or 3hp in this case.

Regardless its a bit more power than the Hyosung then. Hmm..

**Bren_chch** · 10th October 2005, 18:55

33 at the wheel... what have you done to it, standard spec is a huge 25 at the wheel!

Look at the blue line. From http://www.rooracing.com/Vtr250.jpg This is of couse the post '98 VTR250. But the engines are mostly the same. They do have cosmetic differences though.

Most likely 33 'ps' .

i've got the site i got the specs from at uni, i'll post it tommorow, but the vt250f redlines at 12500rpm not 11000 as in that dyno test

**gamgee** · 10th October 2005, 19:28

found the specs for the vt250fe, it was PS, just about to read the difference with ps...
although this one only reports it as 40ps but i'm sure i read 45 for the vt250f:
