Hey guys, on my 17 R6 I low sided in a race and bike slide then flipped and managed to tumble itself. After examining the bike, I found out the lower triple clamp bump stop got sheered off. I removed the forks and grabbed a straight edge and a square level checked the bottom at looked to be flat, i also checked diagonal for flatness, I did the same with the top triple clamp. Bolted everything back together, and I find my wheel is pointing slightly to the right. I figured no problem, loosen the fork clamps and top and center the forks, that didnt work. My question is there a more precise way to check these triple clamps?
You either need a measuring jig or a granite measuring plate. If the bump stop broke off, you need a new triple anyway. And the forks need to be broken down and rolled out in v blocks and have runout checked. What you did doesn't mean anything.
Forks have been checked and spun on a rolling on rollers to check for run out and there straight. I will pull the triples clamps and lay them flat on glass. Another question does the center rod on the stock lower triple clamp have an offset to the forks tubes or are they parallel? If my clamps are straight ill probably take them to a machine ship and have them add some bump stops, because bikes got to be ready for this weekends race.
They are parallel and they have an offset. I'm not sure you understand your question. The steering stem isn't bent, the lower stanchion is.
I pulled the triple clamps, I wasnt able to get it to square up propely because the center post stanchion, the bottom protudes just a bit. I need machinist blocks to lift the sides up properly for to level it out. Thankfully I found two of the same size allen keys that propped the bottom and verified that the lower is bent about 2mm. I will see if a machine shop can do anything tomorrow. I doubt my dealer would stock this triple Thank you for your help
No luck on trying to get this triple clamp straight, we put the thing on a vise and tried twisting it with a huge bar. We tried using a big press no luck. We tried heat, even though not the best idea for cast aluminum. This thing returns back to the bent shape Trying to source a new clamp, all dealers near me do not have stock. ill try my buddy who runs a race team with a fleet of r6's
Mike, Do you happen to know if the 2016 R6 lower triple clamp will work on the 2017 R6? Judging from the photos they look identical, but part numbers are different are slightly different 2016 2CX-23340-00-00 2017 BN6-23340-00-00
They are different. 17+ is 54mm. 08-16 is 52mm. Edit: Actually, I'm not 100% sure on the 2016, specifically. 08-15 (13S-23340-00-00) is, for sure, 52mm. And the 17+ is, for sure, 54mm, but the 16 was an outlier year that had different forks than 08-15. I'm not positive on the dimensions of the lower triples.
Looks like the 13S-23340-00-00 got superseded to the 2CX-23340-00-00 When you say 52mm vs 54mm im assuming the fork diameter is different.
That is definitely the case. I remember reading that with the 2017's they went to the R1 fork which had a bigger OD.
Yes. I know for a fact the 17+ tubes are 54mm at the lower triple and the 08-15 are 52mm at the lower triple. I'm just not sure of the measurement on the 16s because the forks were different. I only ever built maybe a handful of those odd ball forks. They were exclusive to the 16 R6. If the part number was superceded from the 13S, like you're saying, they're 52mm and won't work. I didn't check that. I'm just going off of memory and the parts I can verify because they're in the shop.
