Single Sided Swingarm

removin the wheel on a DSS is probably just as fast as a SSS on a fully raced bike. the sprocket stays on the bike and theres only 1 nut to remove.

Please stop trying to put rationality behind an irrational choice. It'll make life easier when you hit corporate america if your soul has already been crushed.

That is a special setup for quick change.  the sprocket is modified, same could be done on the SSS

I wonder if bike races required pit stops, if more teams would go the SSS route.

What do you mean "if" It has been going on for years. No a tire change on a SSS isn't faster than on a DSS, with race set-up. Go watch a 6 or 12 hour race and see for yourself.

Yea, i meant in a race application. Lord knows why you would need that type of setup on a street bike unless you got bling and lightweight on (MW2).

For a SSS, the Sprocket is already separated from the rim. Just the wheel comes out. Thats why i dont see a real benefit to SSS. Their both pretty make the beast with two backsing fast. it almost comes down to who makes a mistake first.


heres some more crazy ass DSS quick changes

Holy shit that's fast!

Vesrah Suzuki pit stop Barber 2009

Vesrah Suzuki, until this year, were known for fast pit stops.
They raced the WERA Endurance Series and the National Championship Series.

^^^ Nice, 2 wheels rider and fuel in 20 sec.    I have seen those guys in action at Road Atlanta and Barber.

Doesn't appear to be. They 6hr races that I have been to, the lap after the pit stop is faster than the one before.

I don't think the rotors would be a problem. They have some pretty trick quick-change equipment. Notice that they don't remove the calipers for wheel changes. Also, I'm willing to bet they keep a close eye on the rotors and wheels as far as wear and how often they're on the bikes, and I'm sure they start each race with fresh brake pads. (with Vesrah as the main sponsor, there should be no shortage)

The entering and exiting the pits doesn't take much time either. Plus, even if they lose as much as a minute, they should be able to lap much faster with fresh tires and a rested rider and quickly make up the gap. Anyone remember the Daytona 200 Mladin won while taking one more pit-stop than everyone else? (3 stops I think) He was able to lap so much faster on fresh rubber that he more than made up for the time lost in the pits.

I've raced many endurance races and worked the pit crew for others. Normally, when you're out there you get into a great zone and you actually get faster. You get tired but once you get into a zone, you don't want to come in. Your laptimes get better and better all the way until you come in. If the next rider goes out on the first lap and goes faster, then the previous rider probably had a tire fading on him, or got really tired. I hate seeing the board to come in when I'm in the zone unless I'm tired, then I'll just try to survive my last lap and keep the bike upright long enough to hand off. That's what a tired rider will do on his last lap.

As far as what swingarm is faster to change the wheel...doesn't matter. You can set them both up to be fast. I prefer dual sided for a number of reasons. Another that has not been mentioned yet is crash protection. During a lowside with a dual sided, you will usually slide on the spools. It's minimized damage to my tail section many, many times.

Or the better rider goes out for his stint.

(a proper) quick change setup for the superbike class uses wider triples/fork spacing so the calipers don't need to be removed.
