That blows me away, Watch the front wheel change they don't seem to loosen or tighten anything. The bloke does put his hand near the brake caliper maybe he's working some kind of a latch?

There is another dude at the front on the far side, he stands up, and grabs the fire extinguisher. when he finishes getting the front axle back in.

Awesome wheel change. It is a great event. I was sitting just in front of where the polesitter (Ito) was for the start.

That's keeping the F1 boys honest...Awesome!:niceone:

I've raced with a few teams in the UK endurance series and they all had full spec bikes with quick release wheels and dry break fuel tanks etc.....
The last team, HMR were very very quick with stops and in fact not far off the time taken in the clip

Pit stops were a highlight of the racing......... great fun.

Does any one know how thoes quick release sprockets work? Ive never been able to figure it out or find a close up picture

There's a fair few variations, but the two I have worked with either have the sprocket fixed to the wheels or captive to the swing arm. The former has two attatched spacers outermost of the wheel and they drop onto runners that position the axle in the correct place. The wheels have different hubs with round fixed cush drives so nothing falls out. To remove the wheel the runners go forward to allow chain slack and the chain is hooked off. The wheel is then pulled back and out.

The fixed sprcket version has a rounded hexagonal "key" attached to the wheel hub that provides the drive. The swing arm has a hub that carries the sprocket then the open carrier that accepts the key. To remove the wheel has to be rotated until the opening is at the rear then the wheel can be lifted free. (All this is with the axle already removed). The problems with the key method is the bearings in the hub allowing for alignment issues and the extra weight the hub assembly adds to the unsprung weight. The problem with the first system is the time taken with the chain, mostly putting it back on. Thats why you see both types in use.

Pits stops are very exciting and pressured, getting them right is satisfying getting them wrong is disastrous. The Suzuka 8HR is one of the greatest races.:niceone:
