| Antihopping Clutch |
This anti-hopping or “slipper” clutch is a must for any
ambitious rider. Everyone knows about rear wheel hopping: heavy braking in a
curve can lead to unnerving shuddering at the rear wheel. Resourceful engineers have
now come up with the solution: the anti-hopping clutch. The APTC is a worldwide
patented slipper clutch that features a unique hub consisting in two parts connected
by an helix profile.This complex mechanism using angled layers for additional friction was developed to
prevent clutch-slippage: under engine-load this system generates additional pressure on
the clutch plates, but when over-running the clutch is able to slip.
The power torque feature of the APTC guarantees riders maximum rear-wheel grip during
acceleration and anti-hopping or “slipping” during downshifting. By maximizing rider
control, the APTC allows for greater speeds going into and coming out of turns.
This design, unlike all other slipper clutches on the market, mak es it also much easier
to pull the clutch lever (~50% less pressure is required) and eliminates clutch lever
vibration, helping the rider saving a lot of energy and sparing himself the discomfort of a
cramped forearm.- A Supermoto rider could appreciate a better control while braking, without any rear wheel
hop even during heavy braking and hard downshifting. The smoother engine output on
the ground brought by the power torque characteristic of the APTC allows the rider to
open the throttle earlier, for a far more rapid ascent to top speed. The absence of any
clutch lever vibration allows the rider, unlike all other slipper clutches on the market, to
pull the clutch in the off-road section of the track, for a better control of the bike.
- An Enduro rider can appreciate better control while braking, a smoother clutch feel, and
better settling of the rear wheel when hitting breaking bumps before a curve. The light
clutch lever load is also a vital anti-fatigue factor in extra long races. You will also notice
the difference coming from a more constant and stable performance of the clutch under
extreme use.
- A Motocross rider on the other side will discover a better control while braking, and,
especially, a smoother engine output on the ground: this form of traction control allows
the rider to open the throttle earlier, for a far more rapid ascent to top speed. The light
clutch lever load brings much less fatigue and arm pump, helping the rider to perform
more laps without going over the limits, consequently committing less riding errors.
