I have 6 cats from 2004-2015, they collectively have over 50,000 miles plus with out any electrical, motor, or catastrophic failure.....I have normal ware and tear which is expected.......the sleds are ridden hard but I also have an aggressive maintenance program in spring/fall........ I believe if you take care of what your riding......cat, poo, doo, yami, they all will run deep into high miles......I do understand things do happen, but that's the minority these days....... now I do have some riding buddies who park there sleds in spring, fire them back up in fall and cant understand why there broken down so much.....I bleed green and am a advocate of cat and there products...... I do have a new zr5000 4stroke and love it, maybe you need to look in that direction........good luck.
