I've been running BST CF wheels for about a year on my `02 Busa. I have found absolutely no negative issues with the BST rims except the initial price. The lowest current price that I'm aware of is about $3,200 for a complete set. I got lucky and paid $2,850. They are works of art with a high-gloss finish and they transformed my Busas' sluggish handling into a profoundly more responsive bike that is easily "flickable"...! I essentially had to relearn how to ride the Busa because of its new directional change/lean quickness. The CF rims are the most
effective mod I've ever made to a bike.
I also added Braking rotors and pads front and rear at the same time and the combination of rims and rotors saved about
15 pounds of
unsprung weight. Installing a BDE exhaust
saved 22 pounds and installing a `99 - `01 aluminum sub-frame
saved 8 more pounds. These mods, along with an undertail and a few other small weight-saving mods, brought my total weight reduction to 52 pounds making the total weight 498. With 168 RWHP, the power-to-weight ratio is 2.96 pounds per horsepower. The factory power-to-weight ratio is 3.55 pounds per horsepower (with 155 RWHP and 550 pounds in stock condition). To achieve the same power-to-weight ratio with the factory wet weight of 550, the Busa has to be pumped up to 186 RWHP.
The rims are tough, strong, light, and DOT approved. At one bike show, A BST rep was actually bouncing a CF rim off the concrete floor (without a tire) like a basketball without any cracks, chips, or other damage to the wheel and... I know of a 7-second drag Busa that runs them problem-free. I do not sell BST rims nor have any financial interest in BST. Obviously, these pricey wheels are not for every Busa owner. But if you can afford them, I can't imagine how you would not be greatly impressed with the increased performance they produce. I am simply a totally satisfied customer who is sharing his joy!
Get them if you can.
