I tried this in the WR forum and no response... I'm considering changing my Clarke tank for a Zip Ty tank because I recently rode WR with a YZ tank and I loved the seating position. Unfortunately, my Clarke climbs a pretty steep angle toward the bars and does not offer such a flat position. I have never seen a ZIp Ty tank on a 426 and I'm wondering how they fit and how flat they are. So...if anyone has an opinion and more importantly a picture they could send or post...well that would be just swell. You can PM me for an email address if you have some pics. Thank again. Maybe a shout from those who have owned both!
