um, you know the latest RR Buell built in carbon fibre, yellow and blue.
Is it a 1340 or 1200 Buell engine? if a 1340 is it a bored 1200 or a HD big block?
ya see I ask cos a chick I know beat one to a win atr the Sound Of Thunder race meeting last w/e she was on a 749 Duc and the RR is a local Aussie guy , the bikes now black with flames on it.
Anywah tried google but got nothing

D, the XBRR is now old hat, replaced by the 1125R, but a few of them are still out there. It started as an XB motor, but has big bore cyclinders and special flywheels and such. The folks racing here are just using the 1200 motor in their xb's, but there is a lot of internal tech gleaned from the RR built into them from the factory.
Just dug this out of my archives:
Buell XBRR features:
1339cc (81.7 cid) Thunderstorm Powertrain:
4.080 inch (103.6 mm) bore and 3.125 inch (79.4mm) stroke
12.5:1 compression ratio
Dual 62 mm down-draft fuel-injection throttle bodies
WAVE-analyzed header and mass-centralized muffler
150+ peak engine horsepower at 8000 rpm (per SAE J607)
100 ft. lbs. peak engine torque at 6500 rpm (per SAE J607)
Buell ZTL2 reversed rotor front brake with eight-piston Nissin caliper
Ram Air system integrated with full racing fairing
To accommodate eligibility in a wide variety of racing classes, an engine modification kit will be available to help conform the XBRR to a wide range of class regulations.
MSRP is $30,995.
Not to mention the 1125R fairing has its origins in the XBRR. But...I wouldn't doubt anyone on any bike could be beat by someone better on a different bike. The RR is no longer produced, but in the right hands, it could be a monster...
A little long winded answer, but I hope it helped.

Those pistons and flywheels do look a bit radical eh?
I read an article that one of the big horsepower items is the new timing gear case design,
which channels oil back into the pump more efficiently.
