This anti-hopping 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.
Experienced riders overcome this problem on hard terrain with a gentle pull on the clutch lever, thereby reducing the transmission of this force to 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 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, makes 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 in addition appreciate a better control while braking, less vibration and sticking in the clutch lever, which translates to better clutch control, and a lighter perception of the impacts on the rear wheel when hitting rugged terrain before a curve.
The light clutch lever load is also a vital anti-fatigue factor in extra long races.
He will also note 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 driving errors.
