    Uneven tread wear Suspension Issues

    Been racing my grom on stock suspension. Just recently put the mitas supersoft mc35's on and have one race day on them. My front tire is shredded and ripped with melted rubber all over it but the rear one is just worn really smoothly. The front looks like my gsxr 750 rear tire after two or three trackdays on it and the rear looks like the front would. I'm used to the fronts lasting but it seems like I have a suspension problem.

    I weigh 200 with gear. I'm trying to figure out if I need a heavier spring on the front or why the tires are wearing the way they are. The other issue is most of my crashes have been losing the rear in fast corners. I think that means compression is too hard and my rear tire is bouncing. Can anyone give me some insight into this?

    The stock suspension is so not up to par for street riding, I can't imagine how bad it must be on the track.

    I agree with the above. I've mildly pushed the Grom on the street (I still have small chicken strips and I haven't touched down a peg yet), but I still feel I'm riding past the capabilities of the stock suspension. You should upgrade the suspension for the track.

    With that being said I've never seen even tire wear on a motorcycle when comparing front to rear.

    I bought an ohlins rear shock and an ohlins fork cartridge kit. I will let you know how it works out.

    Sweet! Definitely let us know because those mods, especially the Ohlin fork kit have been on my radar.

    As others have said, the stock suspension is severely undersprung for anyone over 130-140lbs. Your symptoms were a result of that and you should see a world of a difference in your riding confidence and tire wear with the Ohlins.
