20-25 mph lowside and they completely saved everything by the swingarm... Not a scratch anywhere by the rear of the bike and even the slider barely shaved down. Look wise, they are basic and very functional with my rear stand. I definitely recommend them.

These fit perfectly in a 2012 Suzuki DL650 V-Strom. It's really serving two purposes in one, spools for bike service, and sliders for protection. On the specific bike, they mount several inches from the ends of the swing-arm. Which, when used for a lift, I imagine is a good thing (chain service, tire changes, etc.) but for protection, perhaps lower on the arm would protect better. But, that's a bike issue, nothing to do with the product. I put these on _after_ a spill that did some light damage to the rear axle bolt and I didn't want to risk serous damage. I obliged this install with a subsequent spill on really loose, deep gravel, the sliders did a fine job - although gravel is impossible to 'slide' on - rather, anything protruding grips the gravel and drags along. The size of the sliders was generous enough to help keep the chain, sprocket, and Scottoiler feed tube higher up off the gravel. Very little damage was noted on the slider (it was a low speed tip fortunately). The slider plastic seemed a little soft compared to others, but I think that would be a good thing since you want to wear off the slider and not the bike parts. The spools are solid as well as the hardware. I'd liked to have had stainless steel M8 bolts and a harder anodized finish, but for the price, everyone should have some of these. Recommended for all bikes.

Useful for using a rear stand. Doubling as sliders provides nice extra protection and peace of mind. Subtle styling, full black so not super noticable on my black swingarm which is good. You may need to clean the threading on the hole in your swingarm to get these in though! 8mm for Suzukis by the way, or at least my Gladius.

These swingarm slider spools ROCK. They aren't expensive, SO EASY to install, and awesome for using them to lift my rear wheel up using my Pitbull stand ( which ROCKS as well ). I can't say how well they will hold up in case of a crash, and hopefully I will never have to review that haha. It literally took me about 5 minutes to install them, maybe less lol. Overall, they do what they are intended for. I definitely recommend them!

Bolted right up to my 07 R1. Looks great and functions just as well.

Bought these mostly for lifting my 2016 XZ-14. but it's nice to think I will get some swing arm protection as well.

Took about 1 minute on each side to install. Just used the correct size allen wrench and they went right in. I have seen folks mention for other brands that they had a buildup of paint in the holes that caused problems with installation but not on my bike.

Main reason I got the Delrin (plastic) version is because the painted versions often get scratched and I wanted black,

easy to place bike on stands, im also using it with a vortex stand. nothing flashy but very functional.

Just grab a allen wrench and throw them on. For sure go with the 10mm. Good size and functionality. Though I have never gone down to know for sure, I am confident they will do the job should I go down.
