Default How do I know if it's a 135bhp or 100bhp engine??


Hi fellas,

I'm in the marked for an CBR1000F 1994 model or newer (SC24).
I live in Norway, and these bikes where sold with 135 horsepower
here. In Germany and Switzerland these bikes only produced 100 bhp.
I know there was at least one number on the bike that would reveal
if the bike is a Swiss/German bike, but where do I find this number?
A picture would be helpful..

I think you're referring to rear wheel hp vs. hp measured at the crank - all CBRs made same hp as far as I know.

Nope...2 different models fo different countries. And it souldn't be a 35% loss from crank to wheel unless it was an all wheel drive car.

Nope. Leftlaner is right. The bikes that were originally imported to Germany was delivered with 100 bhp instead of 135.

But how to tell if its a 135 or 100 bhp bike i don't know...

One (stupid) way of checking is top speed testing... It should be hard to get it past 240 km/h... Another way is removing one carb and check the inside of the rubber tube intake, the lower hp is from a restriction in the intake, should be fairly easy to spot.

BTW! Leftlaner, first norwegian?!!![sm=groupwave.gif] Welcome! Where in Norway do you live? I work in Norway...

I guess the restriction from 135 to 100 hp is removed on most bikes by now. The restriction was done by the intake rubbers, which have a smaller inner diameter on 100 hp engines. It is easy to carve them up to full diameter with a scalpel. One way to see if the bike is full power or not is to test the top speed. It should be about 255 km/h (GPS) on a unrestricted bike. I dont know the top speed for sure on restricted bikes but guess it must be close to 10% less.

Hey! I looked at the price of those rubber peices. $44.75 USD + shipping. Ouch!
I was going to suggest replacing them reather than cutting them out. Not at that price.

What about the 105 hp American 1993+ models - can I carve the intake rubbers and gain some hp? are we talking crank or rear wheel hp?
