Hi all.
I owned and raced a GSXR 1100 some years ago. To lower the bike for dragracing I bought an ohlins rear shock and wound the preload as much as possible - got 4 inches lower in the rear.
In front I cut the internal spacers down to use with aftermarket springs that were longer than stock for street riding. This same spacer worked well with the stock springs to lower the forks internally 2 inches. I then slid the tubes 3 inches in the triple clamps for a total of 5 inches lower in the front. I did have to pull the front fender and side plastic panels for tire clearance issues. This setup had my open header 1 3/4 inches off the ground but I made tech at 3 different tracks (2 inch min.). Slamming this much (as well as weight losses and some other minor engine things got me from 11.3 down to 10.6 on a stock engine.
Any way I'm making a complete list of the mods I would do and in what order I would do them to take a new busa to pro street. I see aftermarket spacers are available to do the internal fork lowering or I could just cut the stock ones if possible - I haven't been inside the busa forks nor do I have access to any to look at right now.
My main question to anyone in the know is can the tubes be slid up the triples (with an aftermarket top that has open holes for the forks) as much as I want ? I have read there is a taper to the external tube that only allows an inch or so before the bottom clamp won't pinch properly. Is this the case ? If so do all the pro sreet guys have their fork tubes cut down ? or rake the head ? to get real low ?
Thanks guys.
