BST Carbon Fiber wheels mounted......

Wow!

Turns like an R6. Stops like dropping a boat anchor. Accelerates harder.

One finger brake from ludicrous speed, stick her into the turn, twist and go.

Awesome.

If you want a new RC51, install these BST carbon fiber wheels.

Wow!

Nothing like lighter wheels to improve handling.
There's a fellow rider in my area that has an SP1 with BSTs.
They're a little pricey for my pocket book, but they are insanely light.
Much lighter than magnesium, which feel like nothing themselves.

Fixed.
That is some serious awesomeness you've got going on there, though.

SaWeeeet! I'm googling all over the internet to learn about sprung and unsprung wieght. I'm discovering just how valuable shedding weight from unsprung parts, like those bitch'n carbon rims, is.
Nicely done 10/10ths. That's just gotta paste a perma-grin on your face!

It's not merely about sprung or unsprung weight.
It mostly about rotating mass at the wheel rim. That's where the handling improvement comes.

A wheel with less mass at the rim and will spin up or down quicker (less flywheel inertia).
Plus it will change direction easier (less gyroscopic inertia).

Now all he needs to do is spend another $2300 on Braketech ceramic-matrix-composite (CMC) rotors and pads, and lose 60% of his brake rotor weight (CMC rotors only weight 1 lb each).

Bah, those rims + those brakes would be a commuter bike for me. I can appreciate the love for this bike, but jeez...

While losing unsprung weight will help, it has a greater effect on how the suspension can react to changes in the road surface. Less weight you are throwing up and down, the better the suspension can work, and the better your traction will be.

Where lightweight wheels really help is in reduction of the gyroscopic effect they generate, which allows easier turning and transitions while in chicaines. The reduction in weight also allows for a reduction in the amount of torque required for a given amount of acceleration, both positive (throttle) and negative (braking).

Yet another thing to consider is where the mass is actually placed on the wheels. A heaver wheel can actually require less torque (because it posseses less inertia) if all the mass is closer to the axis of rotation. The further out the mass, the greater the effect, and it is not a linear relation:

Torque = (mass) x (radius) x (radius) x (angular acceleration)

So for the same mass moved from 1 inch away from the axis of rotation to say 3 inches away. The required torque is nine times greater for the same mass and acceleration.




Sorry I am a bit of a nerd. A nerd that is four months away from a bachelors degree in mechanical engineering.

Shoot, didn't see subsailor's post. Guess that is what happens when you don't click refresh before you post!


Very nice 10/10ths. I've been very happy with my oz wheels too. I was close to buying a used set of BST's, but the guy sold the bike with them a day before I saw the for sale ad. Then I bought my OZ's right before your wheels came up on eBay, damn the luck.
