Lightech Chain Adjusters Yamaha YZF-R6 17-20

For 2018 R6 the axle has to be installed reverse. The self locking nut ends up on the drive chain side. I'm going to install the adjusters upside down so the self locking nut is on the OEM side. On the right, or non drive chain side. Awkward to torque the nut from the drive chain side. Besides the axle carrier slide has a partial pocket that will ultimately collect crap. If installed upside down, meaning the laser etch is point to the ground rather than the sky, less crap collecting on the axle carrier slide. The laser etched marks are not visible on the non nut side. You would have to mill the partial arcs flat so the marks can be viewed. Sure you can rely on the audible clicks but what is the point of the laser etch if you can't use it. Nonsense. As the Brits like to say rubbish. !@#$ing Italians. Go figure. Not even 1 thread is exposed on the self locking nut. I'm a mechanical design engineer with over 25 years of aerospace industry experience. Industry standard is 2 exposed threads. Self locking or not. Properly torqued or not. Aerospace, automotive whatever industry. This is asking for trouble. Will have to keep an eye on it time-to-time. I'm going to see if the swing arm main axle self locking nut will thread onto the rear wheel axle. Same size nut but have not verified thread. The swing arm nut is thinner. May get 1 or 1.5 exposed thread if it works. Granted most consumers won't even bother with this minor design flaw, but I don't have to explain, we all have seen stupid things done by smart people. In our industry we call it idiot proofing. Hence the minimum 2 exposed threads. I torqued all the mounting hardware per instruction and the axle carrier binds against the housing, because the housing is made of aluminum. The mounting screw that replaces the OEM adjuster screws with the lock nut apples tension on the housing and the two housing rails encapsulating the axle slider bows and pinches the axle carrier. This requires more torque to be applied to adjustment nut. May not bother most consumers. I applied less torque to the mounting hardware so the axle carrier does not bind and used blue thread locking compound on all mounting hardware. Lightech needs to go back to the drawing board and improve on their design with the next gen. Design is an iterative process. Always improving. Yes I'm being critical, but this part is not exactly a cheap component and it is a critical part on the bike. If the less than industry standard exposed thread fails and someone ends up dying or getting seriously hurt because of it, Lightech will have a lawsuit on their hands.

Bought this for a 2017 R6. The black wasn’t in stock so I settled for the cobalt blue. Very neat product. Don’t realize you need them until you have them. If you have a ‘17 R6 don’t make the same mistake I did not paying attention to the instructions. You have to flip the axle to insert from the brake caliper side for it to fit in the holes.

Another quality product and extreme fast shipping from STG. This made adjusting the chain a thousand times easier and also added the bling bling look to my 2018 R6.
