Thank You FB1, can you please contact my friend and colleague Mr. HotRodZilla and have him read this well informed statement so his nose can start bleeding? Thank You and Good Night!
The Motovation sliders for the FJR are actually nylon with aluminum alloy inserts.
The OES sliders are machined from Delrin, with aluminum alloy inserts.
Delrin is much faster and easier (cheaper) to machine than nylon which is one reason why OES can sell their sliders for less. Both are good engineering grade plastics but nylon has certain properties that make it the better choice for a slider. Nylon has higher abrasion and impact resistance, so it will gradually grind down as it slides down the road. From what I read when I researched this 2 yrs ago when I bought my sliders, Delrin is more likely to come apart in chunks if your bike goes down sliding. If it chunks off, it is not going to offer a lot of protection for the side of your bike.
Both will probably be fine if they fall down in your driveway.
Ha...The difference between nylon and delrin is neglegible. Just like the aluminum oil filter covers Skooter posted up, a person could make 100 sliders a day with a good lathe. Nylon is cheap, comes in different colors, and can be bought in the spec'd diameter. Delrin is very close, and one's "stand up to a sliding crash" qualities will not show any improvement over the other. Anyone dumb enough to think that two 3" nylon tubes are worth what Motovation charges deserves to have their money taken.
If you want a slider that will not grind down in a crash, go buy aluminum sliders. Of course, they have been known to "grab" the pavement and flip bikes to the other side, causing complete destruction. Neither nylon nor delrin will do much for plastic protection in an actual get off at speed. They are supposed to keep the frame from tweaking, not protect plastic.
