Condition: New Special feature: The pucks are solid and not hollow, made to withstand a greater impact. Brackets are designed NOT to rotate in a lowside. Material: UHMW-PE (ultra high molecular weight polyethylene), solid steel brackets finished in durable black powder coat.Slider dimensions: approx. 4" in length, 2" in diameter NO CUT or plastic fairings modification required Fit Models: Triumph2006 - 2012 Daytona 675 / Daytona 675RThis purchase is for a set of frame sliders for the Triumph Daytona 675. The sliders feature a new design of a complete solid puck without a hollowed-out center. This increases the strength and contact surface to about 30%. The bracket is bolted to the engine mount and the aluminum spacer is bolted to the bracket. The slider puck is then screwed on to the spacer. Since this spacer is made of solid billet aluminum there is no need for re-tightening the engine bolt in the long run where you have to do so with plastic slider as the plastic would gradually give in and therefore making the bolt loose. The brackets have two attachment points preventing them from rotating in the event of a low side. The material of the puck is made of UHMW-PE (ultra high molecular weight polyethylene), a tough plastic with good strength, wear resistance and dimensional stability. It is more dimensionally stable than Nylon and used in many industrial ball bearing and friction reducing applications. Compared to Delrin, it is softer but tougher. Delrin is harder but more brittle. It is an ideal material for frame sliders since it can absorb more impact force onto itself and therefore reduce the impact on the frame and engine. The slider pucks can be inexpensively replaced in case of a low-side. We use highest grade commercially available 12.9(177,000 psi in tensile strength) wherever possible. Rest assured that you are getting the best material commercially available.
