7075 T- 6, aluminum alloy
to a long-wear-ing, high-strength,
outer ring. The result is
a sprocket that wears like a steel sprocket but isn’t as
heavy as steel.
VERDICT: The Twinring sprocket weighs 12 ounces
more than an all-aluminum sprocket and 12 ounces less
than an all-steel sprocket, but it lasts approximately
three times longer. If you are a smart investor, the
longer-lasting Twinring will pay off its $30 premium
by not only lasting longer itself, but by making your
chain last longer.

GPX 6. 5 NECK
The GPX 6. 5 is Leatt’s latest creation. It is stronger,
lighter, narrower, easier to adjust and comes with 0-, 5-,
10- and 15-degree stops.
VERDICT: In an effort to cater to a wider demographic
and address riders’ complaints about helmet interference,
Leatt moved the GPX 6. 5 frame lower. This allows riders to
turn their heads without hitting the neck brace (especially
noticeable to riders with short necks). This makes the GPX
6. 5 more appealing to some riders, while the safety-conscious can stick with the taller Leatt Pro Lite brace.

JGRMX ADJUSTABLE YZ250F/450F
Joe Gibbs Racing’s adjustable subframe for YZ250Fs
and YZ450Fs lowers the subframe via heim joints that
attach to the frame. Every 360-degree rotation of the
heim joint is equal to a 3mm change in subframe length,
which, when multiplied by the angle to the rear of the
subframe, can account for lowering the rear of the
subframe as much as 8mm.
VERDICT: How low can you go? Until your rear tire
hits the underside of the fender. We loved this product,
but it does require care in setting it up.
DIGITS: $450.00 (complete), $180.00 (with your
subframe)— www.jgrmx.com or (877) 905-4769.
USED IT, ABUSED IT, MISUSED IT & LOVED IT
CYCRA RACING REBOUND HAND
Just like a folding lever, Cycra Racing Rebound hand
guards pivot forward upon impact with the ground and
return to their original position automatically once the
bike has been picked up.
VERDICT: The MXA test crew thinks that Cycra’s
Rebound hand guards are the best in the business. Why?
(1) They move during a crash to avoid breaking and
return to their original position. ( 2) They don’t chatter
or bend back and slap your fingers. ( 3) Installation is a
breeze. ( 4) They aren’t too big or too small. ( 5) Test
riders’ hands never touch them while riding.
