Suspension Question

Hey all...

I have a 2010 Triumph Tbird. I picked it up used. I've had it for nearly a year.

The owner before me put on Progressive Suspension. There isn't an application from Progressive for this bike, so he used shocks that were supposed to fit a HD. Same size and weight bike.

Anyway, I was talking to someone recently. We were talking tires. I told him how, because I wasn't as diligent about my tire pressure, my front tire started cupping. And now that I have new tires on the bike.

Once we got around to talking suspension, he said that he believes that my tires started cupping not only due to the tire pressure but because my rear suspension is lowered.

He suggested that I slap on my stock shocks. He said not only will the bike handle like it was supposed to originally, but it should help with the tire situation.

Can anyone back this up...could use a little help from the crowd.

Thanks,

Chopping/cupping tires

I don't think lowering your suspension has a thing to do with your tire problem. I lowered my T-bird by shaving the seat thus leaving the suspension stock I'm on my 3rd set of tires and EVERY FRONT TIRE CUPPED! I've watched my airpressure, adjusted when ridding double, tried different pressures and I can see the Metzlers starting to show they want to cup again. Even the Metzlers on my V65 Magna are showing the same thing on the front. It cant be the rake of the fork both bikes are raked differently, one has forward controls the other mid., one bike new the other 37years old! I just think its the spacing in the water channels and siping on the tire.

Those that say "OLD IS SLOW" have never ridden a V65 Magna!
