Its suppose to be A=dry, B=mix, and C=wet conditions or 1340,750 and 600. I think its a waste of time they could have used that technology $$$ by adding a radial master cylinder for the front brakes instead.
I just picked up a Busa on Friday. 2005 model with only 7100km on it. It is immaculate and completely stock-standard.
I have ordered a Yoshi TRS kit, Soupy's lowering links and bar riser, Galfer braided lines (brake and clutch), a HotBodies hugger, an iridium blue double-bubble screen, Roaring Toyz lowered kickstand and T-Rex frame sliders.
Here's what she looks like now:
I'll post another pic when she's fully upgraded.
congrats on an awesome score! mileage on the bike?
