Damn I hate being a noob again! Planning on racing a XB12R and hopefully will have one secured next week but I have a question. I realize the XBRR is a limited production racer but I have been offered a couple XBRR's pretty cheap. Is the 1125r comparable on the track to the XBRR? Reliability from those that do the Moto ST series? I was thinking about the possibility of supertwin. So, the follow on question is how cheap would an XBRR have to be in order to buy instead of a 1125R

I'd say really cheap. Remote starter for one. As far as I know, the XBRR has been abandoned. Pretty expensive to repair. The 1125 has at least finished a Moto-ST race.(and won) Walt Sipp is the only one ever to take the XBRR the full race at the Daytona 200.
I'd run the 1125, but that's me.

+1 on the 1125R!

I was told by Terry Galaghan at Hal's that you better have lots of time and money to race an XBRR. It basically needs to be torn down and at least inspected after every race. Not because it's a POS, but because it is just built to the ragged edge of that motors performance. Plus you'll need access to a dyno on a regular basis to keep it running right. Then there's the cost of the 114 octane leaded race fuel, a must because of the compression. I'd buy the 1125R and never look back! This is the direction that I think Buell is going to direct most of it's racing attention. There are a ton of race only parts for it already, and with the AMA class structure the way it is for 2009, I think there are more good things to come. I had the opportunity to ride a bone stock '08 1125R at Road America Inside Pass last year, and man what a track bike. And that was stock. I'd love to be able to ride a fully track prepped version with a proper tune, chain kit, and some DOT's! I'm looking into swiping one up at some point this off season, probably as a street bike, with a few track days and a sprint race or two thrown in for good measure.

1125R without a doubt. Much less hassle.

That is some good information and the price of the 1125r compared the 1098 is a no-brainer.

You can race a 1125R fairly inexpensively at club level once underway.

The initial moderately high cost items needed are the bike, a chain drive conversion, aftermarket rear shock and at least proper springs for the forks, you will also need a belly pan and Buell race brake pads or equivalent, also a steering damper is required by most clubs, assorted fluid catch cans are needed as well as safety wire and non glycol based coolant. You can leave the motor basically stock and be competitive as Higbee has shown. Add icing as money becomes available like the 6 mm front rotor and radial master cylinder, full faring/plastics, gp shift kit etc,etc. Obviously tires will apply no matter what you race.

You would need to possibly find a salvage title 1125R that is straight or at least only needing minor repair to help keep the startup costs down, because with the basic baseline items I have listed just to get started with finding the cheapest used not salvaged bike or new bike you are in the realm of 15 to 18k and thats with you doing all the required prep. You could also sell the stock stuff to help recoup some of the costs.

It sure is cool to see Buell Racing come alive!!

WERA123,

I plan to run an XB12R in the WERA North Florida Series next year. Maybe I'll see you at Robeling?

we race xb's, RR's and 1125s. The RR's are fast, but do require a lot of maintenance if you are running the hell out of it. The XB's are pretty good. You have maintenance but not to bad. So far our 1125 has been pretty good. Haven't raced it much yet but so far very little maintenance. We have a Penski shock,swing arm conversion, steering damper, Buell race forks, Rocket exhaust{still developing} and a GP shifter. We also have a race ECM and it is dyno tuned. I think the 1125R is probably the best choice. Bike may cost a little more to get but in the long run I believe it is a good choice. Second would be an XB. I like th RR but you need a lot of time and a good bit of money to race it.

Paint Shalker:
I put in a lot of miles at Roebling back in the early 90's on a LWT bike.

This is good information about the 1125r. I could see where Buell may go further in the water-cooled direction in the future.

The Buell like all the other race bikes I have prepared sounds to be straight forward with the addition of the chain conversion. In the past I always concentrated on the suspension first.

what about the engine life of the XBRR with the full circle crank , i know there is a top team that uses or used this solution ...don't know about results.

Wera consider what I'm going to say like a personal ( and un-popular) consideration...i'll never change an air-cooled xb for a 1125(even with a so big difference in power).
why you don't consider to buy a cheap used race xb and invest on a rebuilt with the 1170/1430 cc conversion ???
XBS handling is unique.
bye Alessio

Most race organizations tend to have more classes for the air-cooled, 2-valve big twins than the liquid-cooled, 4-valve twins.

I think if you're looking for overall points, the aircooled motor might actually make more sense than the liquid cooled - but there are a TON of related factors to consider.

There, I didn't help a bit now, did I?

XB12R will definitely be the race rig for next year, but considering a second bike and I leaned towards the 1125r but I will probably go for a 2nd XR with a different engine configuration. It would be even better with the parts commonality

XBRR = grenade / headache / money pit. I really enjoy the XB's, but that's just my preferance. There is a lot of stuff out there for them, and people have already done the R&D work on them. Their parts as well as whole bikes will be getting cheaper (my opinion) as more and more people jump ship to the Rotax. By the 2010 season the Rotax's will probably be well sorted out and the aftermarket will be bigger and more able to support them.
