Just curious as to why tire wear gets exponentially worse as you go up in class? Is it the top speed? Weight? HP? Torque? Acceleration? This is the second time I've heard this and one of the influences for me to stick with the 300 as my track bike. The cost in consumables and maintenance just seems disproportionate to the performance for bigger bikes IMO - especially in your SV650 example which I'm looking into as my #2 track option. Just thought thought it would be more linear.
Mostly itís acceleration (hp/torque) and braking, plus adding weight doesnít help. The more power you have, the more demand on the rear tire to not brake loose. This generates a ton of heat, which transfers to melting rubber. Running much faster speeds, means using a lot more brake into corners. This also generates heat and melts the rubber. Doing this over and over and itís very easy to wear out tires.
On the little ninja, with 30ish hp, you are not going to spin up the tire or lose traction (under normal conditions). Then, Without a ton of power, you donít want to lose speed, so you carry your momentum into the corners. The lack of hard braking keeps the rubber on the tire, too.
I hope I explained that decent.
