Womet-Tech Rear Axle Spool Slider System for Yamaha FZ-07 / MT-07 / XSR700 / YZF-R7
Womet-Tech Rear Axle Spool Slider System for Yamaha FZ-07 / MT-07 / XSR700 / YZF-R7
I've had these frame sliders on my FZ07 for several years now. Easy to install and remove. They're very useful when I need to prop up the rear tire for maintenance. Not only that. Great crash protection for the rear axle. I low sided and the bike hit curb. The rear axle bent and part of it snapped right off but no damage to the rear axle. If I didn't have the sliders on. The brunt of the impact would definitely go straight to the rear axle frame and wheel with all that inertia at 60+. Luckily it didn't damage anything. Did its job and I'll be getting another set to replace them. Sliders definitely mitigated a costly repair for this crash I had
