I had a 1098R for a couple of years, I dont know the 1198 intimately but I do know that it had some significant upgrades to the 1098 including a quickshifter, better traction control and far more sophisticated electronics along with a claimed 180 bhp. The 1098 is a masterwork for a publicly available superbike and the 1198 took that even further.
How much does your buddy want for his? I might be interested.
It's my understanding that the 08 1098R (red)has the more basic T/C that needs the std mufflers fitted to work (won't work with the termi kit and it's ECU apparently) and a close ratio gearbox that is known to fail, and the 09 (Bayliss) has the more sophisticated T/C that is significantly better. the 09 has a stronger gearbox as well, all of which came on the 1198R along with the Alloy tank, the QS and the "corse" fairing colours.
All great bikes, but as far as the engine goes they're pretty much the same, 180hp was claimed with the std set up, 186 with the 70mm termi kit (with ECU and A/C, no cat or flapper).
I love my Bayliss, i met a guy at a show recently who had an 1198R, ironically he also bought a Bayliss as part of his self managed super which lives in it's crate, unfortunately for him the 1198R is much more collectible, especially here in OZ because we initially got 150 of the Bayliss model, then got more that were allocated to Japan but didn't sell. His much rarer bike gets used and the "investment" that's not as valuable sits in a box......
Did the US get the Exhaust kit in the crate? mine came with a cover, data logger, lap time dongle thing, stand and the 70mm full system all included.
