Any one have any info on what year they showed up on scene? AKA ... what year are they eligible in vintage classes?
Dale Walker had them for drag bikes in the late 70's. I'm thinking he had them for most applications in the mid 80's.
Previous post...I guess that relates to air shifters...there might be something else about other quick shifters but I didn't find it yet. Regards, Chad
I did take a look at the rulebook before posting. I appreciate your input. It was my interpretation of the passage that you quoted, and specifically what you underlined, to mean that in the case of a disabled rider needing modern technology to assist them on a vintage bike dated far enough back that the date cut off didn't allow the use of that technology, that it could be approved on a case by case basis. I'm not disabled, so I don't think this rule applies to what I'm asking, as I'm not asking for any special treatment. I also think that an air shifter is different than a quick shifter, but I may be wrong. The general consensus that I take from the component section and the technical section is that if a component was used during that time period then it is legal for your class. Hence the reason I asked about the quick shifter time frame. I looked myself but was having a hard time finding info on its initial use.
Had my previous post written up and forgot to hit send after getting distracted at work! Either way, I cant find anything that says they are NOT legal, and they were being used way before my before my cutoff date if Kev59s info is correct. I'll do some more research but I think I'm good if I can come up with proof.
I didn't see what bike and what class you wanted to ride with the quick-shifter...but I'm guessing if you are riding V6...maybe even V5 or above, there probably won't be an issue. I think people would just be glad to have a bike on the grid. I wouldn't protest you for passing me while using your quick-shifter...but don't pass me in classes below V8 with radial brake calipers...I get butt hurt over that! Regards, Chad
Quick shifter and slipper clutch are fine in V6LW been running them for years in the FZR. Did the research and asked permission a long time ago. Don’t remember the research at this point but it’s good.
There was a quickshifter on the Virginia Breeze Endurance bike in 92, up shift only, think it was Dale Walkers stuff.
