Hand Controls S-III and Trikes

We offer a comprehensive choice of controls tailored to individual requirements. The most common are full hand controls: All of our vehicles use CNC billet calipers which displace a very small amount of fluid when operated. This enables all brakes to be linked to a single lever which can be hand operated, providing excellent braking, and a firm feel on the lever.


Gear changing

For shifting gears, the Klicktronic system offers very effective control of the gear changes with electric push-button operation. The servo mounts directly to the gearbox and guarantees no missing gears or false neutrals.



Non K40 S-III’s can be fitted with optional BMW’s electric back-up reverse. The K1200LT 5-speed gearbox has this facility and can be fitted to all of the non K40 K-series motors, including the 1100. It is a superbly engineered and provides a perfect solution if reverse is necessary.

Reverse is available on all Grinnall trikes.
