To be honest, I've only been on 2 bikes with them - a KTM LC4 in SM trim and my Husky 510. They were great on those to applications.
I've pushed the SMT pretty hard in some corners and felt the front end not track right. My first guess was that the stock Conti's are crap. The people on the interwebs seem to agree. I'll have to try another tire to compare. That won't be until this one looks funny.
I've read that a couple people have them on their LC8 SM bikes and really like them. If I can find a reasonable price on one, I'd really like to try it.
990SMT, 640A, TXC450, TE510, ATC350X, ATC200ES, 550MXC, BW200. Need more space in garage.
