I just finished lowering my 05 Busa LE 1.5" in the front and 2.5" in the back. I made everything myself and it only cost me about $10.00. I used 3/4" pipe for the risers on the front and replaced the stock bolts with 6" bolts and locking nuts from Fastenal. The rear was 1" plate steel (1/8" thick. yes, yes, I know steel is heavier than aluminum but we're talkin ounces here not pounds) Remember though on the rear, every 1/2" on the link translates to 1" at the wheel. I would highly recommend that if you like riding twisties, don't go any lower than 2.5" in the rear because the lower fairing and exhaust will scrape the ground in a hard turn. Also, unless its a show bike, 1.25" is about max in the front with risers, right now at 1.5" my brake resevior hits my windscreen. This can be solved with an aftermarket windsreen but if its stock, I'd go 1.25". Also, my plastic under the nose hits the front fender on big bumps.
All in all, I love the look of the bike lowered. Super Agressive. The riding position feels 100% stock until you set your feet on the ground and then it feels like a freakin sled.
I love it!
I'll try and post some pics soon
Just my .02 and experiences.
Oh yea 1 more thing.
The kickstand. If you heat it up and bend it, make you sure you check it against your footpeg when it is in the raised position. I didn't check mine but I got lucky, it lays right next to the scraper hangin off the footpeg. About 1/2" away from it.
