Tim McArthur wrote about Translogic QS2 Quickshifter:

"I put a Translogic QS2 on my GSXR600, and found that it was very easy to install. The instructions were pretty clear (yes I'm a male and I read the instructions!), with all the connectors ready to go it was quite literally plug and play.
I have been using quickshifters for a few years on 125GP bikes, but the QS2 really impressed me. On my old quickshifter I used to bump it with my foot which would cut the bike when I didnt want it to, but have never had this problem on the Translogic one. It's also the first quickshifter I've used that doesn't create really harsh gear changing at lower RPM when short shifting.

All in all I'm really impressed with the quality and function of the Translogic quickshifter compared to many others that I've seen and used"
