New chain but, what size?
porter:
The 2014 on face lifted(ruined to some) models use 17 tooth front sprocket, 41 tooth rear as oe. The chain is a 525, 116 link but as Gert say the two I've bought have came with 120 links so had to shorten.
You can go down one tooth on the front to a 16 or two teeth up on the rear to a 43 without touching the chain. Both are popular mods but I've tried both and like the oe setup better.
The newer models don't have the overdrive top gear of the older bikes so if you lower the gearing with one on the above sprockets it makes the bike much more buzzy on the faster roads, motorways etc.
I've seen that JT always say a 42 rear but I don't like their sprockets so wouldn't buy( had one once that was oval from new).
Gert:
I wonder whether anyone has perhaps had the L7+ Veek traction control warning light come on, after changing to a non-stock sized front or rear sprocket?
Would there be a difference for the ECU programming to detect the new sprocket size as wheel slippage?
kwackboy:
Gert , the traction control, I believe, uses the ABS sensors, it shouldn't make any difference what size sprockets you have.
Also, if the speedo is connected to the ABS sensors , changing sprocket sizes shouldn't alter the speedo.
porter:
I seem to remember someone had difficulty with the traction control after changing the front sprocket to a 16 tooth over on Stromtroppers. I had no trouble with either sprocket and preferred the 43 rear over the 16 front.
On the 2014 on 1000 the speedo works of the front wheel and sensor so you can change away and not affect the speedo.
Gert:
Thanks. I think that the above is worth keeping in mind in case the TC starts lighting up after anyone changed to a non standard sprocket on their 17+.
