I can't remember the figure...

But I THINK, it was about the same as a Toyota Celica...

Depends greatly on a R125 how much you weigh, i know by the time I had finished I had removed 10Kg from the bike. It was vastly improved.

That wasn't me, mine was done using lots of titanium, a lathe, and selecting the right bits. Brake lines are a surprising area where you can really save some weight.

Worked it out manually myself, I've got about 65bhp/ton, that's with the assumption that me and the bike still weigh 200kg. Though she's got lighter and I've not got heavier ;D

it's about 11.75 at the wheel, keeping everything standard

I've seen standard dyno printouts around 12.5/13, so I used 13 :p
Were it as low as 11, I'd have 55 instead

The formula is simply Horsepower/Total Weight in tons. (ie. 13/0.213) so it's about 61 per ton.

Either way, far more than any 17 year old's car will have :p
And the weight means so much more in the city. I got a friend with a 90hp Polo, and I rinse her every time.
