RIDER AN ALYSIS
I was fortunate enough to meet
American-Brit David Cork at the
American Racing Team launch
in Calabasas recently, and
when he asked me if I wanted to
try out some Pro-Bolt titanium
pieces, I thought he was joking.
These are real race bike
pieces, exquisitely crafted and
they give a significant weight
saving over stock.
David sent me a titanium bolt
and nut kit consisting of sprock-
et nuts, front brake caliper bolts,
front-axle pinch bolts, middle
and top triple-clamp bolts and
handlebar clamp bolts, a rear
axle nut, sump plug and an oil
filler cap.
You must be careful not to
overtighten a titanium bolt,
so a torque wrench is a must,
and everything is fitted like the
proverbial glove.
However, there were a couple
of pieces that were heavier than
stock. The oil filler cap is nearly
50 percent heavier (titanium
versus plastic) and the handle-
•VERY BLING!
•SUPER LIGHT WEIGHT
•PRE-DRILLED FOR LOCK WIRING
•SOME PARTS A FAIR BIT
HEAVIER THAN STOCK
bar clamp bolts for the top triple
clamp are about 40 percent
heavier. Needless to say, I did
not use those pieces because if
I'm trying to save weight, I'm
not going to add any.
In all, the titanium bolt and
nut kit came in at 305 grams,
while the aluminum stock bolts
and nuts weighed 452 grams.
That's a savings of 33 percent,
mainly in unsprung weight. I'm
not going to lie and say I can
feel the difference on track (I'm
not that good a rider), but less
weight anywhere means less
mass to accelerate and there-
fore, faster acceleration. And
when you're 190 pounds on a
600cc supersport, you need all

the help you can get.
They are lovely pieces of kit,
and I'll be interested to see how
they last in terms of their finish
over the course of the season.
