Quick change conversions are roughly $1000-5000...So no I don't think your typical racer uses them, its not required unless your racing endurance or maybe Daytona. Without pit stops why spend thousands on a system like that... Also all that I have seen require a race spec under the swingarm mounted rear brake caliper, I don't think you are allowed to even change your rear caliper in a lot of race classes..
I know of no local roadracers who use quick-change wheels, and it is for a very simple reason: there are no local roadracing organizations that run races long enough and on fast enough tracks to warrant having to change wheels that quickly!
Normal races at SOAR and RACE are well within what can be done without a mid-race pit stop. Even at the nationals, the races are still not long enough to need a pit stop. In many cases, the rulebook dictates what the race teams run. There is always the weather situation ... but the most common solution in that case is to have two bikes, one set up for dry, one set up for wet.
SOAR runs an endurance race every weekend, but this is at a regional level and it happens at a track that has comparatively low speeds (Grand Bend) so it has generally been found that one set of tires of a well-chosen compound will be enough to go the distance.
The Daytona 200 is a whoooooole different ball game.

spacers that are attached to the wheels, and don't fall off as your trying to install the wheel....You can make them yourself or there are bike specific kits. All the aftermarket wheels I have bought came with captive spacers...

Hey! I have a quick change rear on my bike!..... and you know me.... or at least I thought you did... pffft....
LOL.
I can also think of another SOAR racer who has the fastfrank QC stuff. Regardless, I agree with you Brian, it's not needed for what we do. I actually don't use my QC rear axle because it doesn't work with my pitbull trailer restraint system. The pitbull TRS holds way more value in my eyes.
This is our second season running Fast Franks system front and rear. Fantastic system at a very economical price! Is it needed for sprint racing, no. Does it make things much easier especially in those situations of rapidly changing track conditions and back to back races ect. Absolutely! Front change in about 15 sec. rear in 10 sec. Graves is nice but VERY spendy!!
Richard, I had no idea
But if you're not using it, ???At a track day, normally there are 3 groups, if they are 20 minute sessions then you have a whole 40 minutes to change wheels. Normally if you go into a track day with a good set of tires to begin with (which you should), there should be no need to change them unless there is a change in the weather and you want to run rains - but most people just wait it out or give up on the day. If you are trashing a set of tires within one track day then either you have something wrong with your bike, or something wrong with your riding, or you are SO fast that you really ought to be moving beyond track days
My new wheels have captive spacers. Just that, will make changing wheels a lot faster. Only problem now is that I've only got one set. If it's raining, I'm not riding.

Oh pshaw Brian... you're starting to sound like a certain someone......................
Can't you use the the older rims you owned? Or will the change in brakes and other bits not make them compatible anymore?
We made our own for GSX-R. Almost more work than it was worth(then again my lathe is a peice of shat). If we can streamline it we'll be peddling them at the track

The ones I've seen aren't all that exotic. Just like a standard spacer with a little lip on the inside end. The spacer is held in place by the dust seal, it just snaps in. If you're particularly rough with your wheel change, you could still knock them out.

Totally compatible. But no more 18" rear tires are available!

Yeah great, but they have only for the GSXR 2006-2012.
I don't know how I didn't think of that before, but my dad owns a small factory in Europe with all kinds of machinery for making virtually anything from metal... maybe I can make specs for him to make me a few. Assuming I measure the stock spacers, what else needs be added to make it a captive? Just a small lip on the side that goes inside, and a bigger outside or what? Same depth I suppose?

Bought an ex factory bike, came with QC system. It helps me, as it cuts down on my wrench throwing incidents when the wheel spacers and brake hanger fall out. Then again i have a rage problem. See you on the track.
