Swing arm travel?

Track racers:

if you could choose, would you have more swing arm travel?

I'm in a kinematics of mechanisms class, and we have to design a new mechanism. I'm thinking about swing arms. In particular, doing away with the arm, and replacing its line of travel with a slot. The slot itself could be modified, changing the arc radius, or even using a straight slot for a truer spring force across the line of travel.

What would be a desirable result in a system like this?

asking racers because that is where all motorcycle tech trickles from.

Yamaha over the last 10 years or so has worked hard to lenthen swingarms while keeping wheelbase the same. I think the effect was to get better bite under acceleration and better compression/rebound control from the shock. (correct me if I'm wrong gurus)

- I got passed by an R6 on 675 south tonite at about 9:55. The guy had to be running about 85. Was that you?

Probably. Hids?

Better bite, as in grip? The longer arm served as a better lever for the spring force?

Or, it meant less radial travel, so less disturbance to the frame.

Yeah - your bikes lights were bright as shit... :D - I bet those lights are nice to ride behind.

Suspension stuff - check Tony Foale, he's a guru of bike suspensions...
