Has anyone made a system like this, at a budget, or is using one at the minute? Are there any of these systems avalible on the market?

I would be interested in the same thing. I had thought of some kind of preferably light weight flywheel/ring gear bolted either just in front of the diff or somehow mounted behind the bike engine. This could use a car starter motor to engage for reverse with perhaps a solenoid acting from the neutral light switch to deactivate if the bike engine/box had been left in gear.

Haven't done much searching yet

Sorry

I see you were talking about a gear shifter not an electric BEC reverse !

Keep an eye on e-bay. I just picked up a full kit for 150 quid, unused. They don't come along that often (last one I just missed out on was a couple of months ago) but if you're not in a rush you can pick them up considerably cheaper than new. Usually sold from people who've bought bikes that had been modified for a disabled rider.

DIY system

Using a Kliktronic - bought 2nd-hand off a forum member. As has been said, keep an eye-out on eBay.

ive just designed the controller for one of these as my final year uni project.

It does shifting based on gear barrel position, with re shifting attempts, spark cut, throttle blips and automatic neutral shuffle.

Im hopefully building a pre-production version at the start of the new year. Designed as a favour to my friend who builds hillclimb cars.

The controllers fairly straight forward to design using a microcontroller and interface circuits.

The bit im not looking forward to is writting the interface software to allow users to set things for their specific engine and gearbox.
