I went for a two hour ride yesterday and found that every time I lay in to the gas my front end would start to vibrate. I would expect maybe a little since there is little weight on the front end, but this was quite violently. I checked my front tire when I got home and it looks to be cupped. I’m going to take it for another ride tonight to try to get a better feel to what is going on. What should I be looking for? I wouldn’t think my front end would be out of whack already. What do you guys think?
