Compare stock clutch to HiT Clutch – Field Test
Field Test
To compare various data between stock (conventional) clutch and High Thrust Clutch.
Application: Veypor Analysis Software
The Veypor Analysis Software constitutes a component of the Veypor motorcycle performance data acquisition system. Aimed at assisting riders in accurately gathering and analyzing their motorcycle’s performance data, it boasts functionalities like horsepower and torque plotting, lap timing, and speed measurement. These features render it an indispensable asset for both everyday riders and performance aficionados.

Comparison
Conclusively speaking, High Thrust Clutch has obvious advantage in every aspect; while there was 2~5% improvement speed-wise, we saw superb 15~ 19% improvement regarding maximum horsepower and torque.
| Record | Stock Clutch | HiT Clutch | Difference |
|---|---|---|---|
| Maximum Horsepower | 8.3618 kW | 9.7687 kW | UP 16.83% |
| Maximum Torque | 10.7988 N-m | 12.8010 N-m | UP 18.54% |
| Maximum Velocity | 88.5110 km/hr | 91.4410 km/hr | UP 3.31% |
| 0~80 km/hr time | 13.5122 sec | 13.1686 sec | Save 2.54% |
| 0~20m time | 2.5209 sec | 2.3979 sec | Save 4.88% |

| 0~400m time | 21.1855 sec | 20.6937 sec | Save 2.32% |
In “0-20m time”, thank for the effective engagement, much less slippage and more acceleration, High Thrust Clutch got absolute advantage in the very beginning, which showed 4.88% time-saving or simply said 4.88% FASTER. Later, since there was no such “slippery contact” period, the improvement rate was slightly adjusted.
1.1~ 1.4 seconds after the take-off, both stock and HiT Clutch reached the peak value of torque, which then went down along with the rise of speed. In the aspect of torque, HiT Clutch won 18.54% over the stock one, as the contribution of shorter slippage duration as well as the “HiT-unique” thrust force by Push Pins.
Take a look at the time throughout the entire experiment, we found that the longer distance we travelled, the more speed difference we saw between these two clutches. Roughly speaking, HiT Clutch performed from 0.1 second faster to 0.5 seconds faster than the stock one. Shown in the Comparison Figure, the distance between blue line (stock clutch) and red line (HiT Clutch) became wider along with the timeline.
Both clutches reached a speed of 80 km/hr when they travelled to 200~ 300 m. And at the end of the whole route, a distance of 400m from start, the meter showed the top end for both clutches were 88.51 km/hr (stock clutch) and 91.44 km/hr (HiT Clutch).
