GSXR1000 Vs Hybusa
Jeano - 20/12/21 at 07:01 AM

Morning All,

why do people use the GSR1000 compared to the Hybusa? Looking at a couple of cars at the moment and i feel if i went GSXR1000 i would be disappointed in a few years?

the 1000 car is lovely apart from that fact.

These cars are very light and very fast.
It doesn't take much horse power to get them moving.
If the GSXR is a newish engine then it will be close to 200bhp and this will take a long time to get bored with.
The Busa engine has a bit more torque which makes it a little more usable on the road but not by much.
Side by side there wouldn't be much in it, but if you have plenty of cash and want extra power the Busa can be made to have a lot of it.

Plus the CSXR1000 revs higher

i thought these were about 165bhp not 200bhp?

Other benefit of keeping it around 1000cc is you can often get away with just a sump baffle plate and an overfill.

To do oil surge control properly on a Busa you're looking at a dry sump system (or at least an oil accumulator like an accusump) which will add a chunk of weight and cost. And a Busa is already likely to be 20kg heavier than most litre bike engines.

A late nineties litre bike engine is probably 150bhp (eg a 4XV R1) but as you get closer to the current day they creep up towards 200bhp.

Depends on what year gixer it came from. Bike manufacturers have been squeezing more power from their engines practically year on year. The 200bhp ones will be the ones from the last few years, the 160bhp ones are the ones from 15+ years ago. The difference is mainly when they are screaming though so in most "normal" use you wouldn't really notice that much difference. Get above 12,000rpm and you will!
