DYNO TESTS - KLIKTRONIC & TECHTRONIC SYSTEMS
We are often asked whether or not you can make clutchless upchanges using the Kliktronic
The answer is yes, you can - simply by backing off the throttle very slightly when pushing the up button. The speed
of operation makes this much smoother than attempting the same thing using your foot.
However if you require a full throttle racing style clutchless change, then we recommend using our system in conjunction
with the Techtronics Interrupt System.
In order to get a clear and accurate picture of how the two systems combine, a Kawasaki
ZZR1100 equipped with both systems was taken to the Techtronics workshop for dyno testing. The results clearly
showed that each system has clear benefits which when combined compliment each other.
The result is an extremely fast and virtually seamless gearchange which can be used for improved performance on
the track. Or simply a much smoother operation in normal day to day road use.
Detailed examination of the dyno printouts underlined our theory that for a smoother,
more consistent gearchange, speed of operation is the key.
Whilst ignition interrupts are widely used on the track they are less commonly used for normal road use. tests
conducted at normal road revs/speed revealed that the whole gearchange process is much smoother
The tests revealed that at the rear wheel the ZZR pushes out 126 bhp @ 9500 rpm.
This machine is in standard trim - tests conducted at more sedate engine revs gave interesting results. Changing
gear at 5500 rpm the output was down to around 40bhp but good enough for 90mph which is typical road use.
The dyno sheet below gives an interesting comparison between gearchanges carried out by foot and using the Kliktronics/Techtronics
The two traces clearly show the difference between conventional foot change and
The peaks and troughs are dramatically shorter resulting in a much smoother and faster gearchange.
This not only translates to smoothness, but also improved performance and less strain on the transmission and drivetrain.
The system is suitable for all machines including bike engined cars, for detailed information on the techtronics
system see our links page for details of their site.
