13 tooth counter

15 posts in this topic

Looking for a 13 tooth countershaft sprocket for a 650r, I see 14 and 15 tooth everywhere but no 13s. Is anyone running a 13/48 and how is it in tough and tight rox?

I have 13/51 right now. For technical rocky climbs I wish I had gone 13/52 but it still does well.

Do you still have to work the clutch a lot? How's it lug and where did you buy the 13? thanx

I just got a 13 for my XR600.. are they the same ? I think Moose had them. I had my local shop get it. It seems, he can sell to me the same price I would get on net with the shipping. So I'd rather give him the business. I think it was around $17. (I also run 13/51)

I had a 13 on mine when i bought it.13\47 It might be ok on rock like Moab,but it looses everything to wheel spin on dirt.Slow,Slow,Slow.No top speed no grunt.

As far as the 600 sprocket.It will fit but... The width where the shaft contacts it is smaller and could destroy the shaft.

51 to a 52 rear isnt that much a difference, one or another would be really comporable. You guys cant do much for speed with that gearing can ya? or is it fairly close to stock?

Try sprocket specialists. They stock fronts and rear for almost any bike. If they don't stock it they'll make it for you.

Can you folks get Renthal bits? They list a 13t for the 650R in the UK.

Mines on order, the 14/48 is to high, 'specially in tight muddy H+H courses. The 13 will take it down about 7%, which should help on the downs, and be a bit easyer to ride - 2nd gear grunt not 1st gear revs.

Does the chain guide need much modifying to run a 51/52 rear?

(Not worried about top speed, no places to get out of 3rd gear for me!)

I ran 13/48 on my first 650R for years. I loved it in the woods. Still plenty of top end for east coast dirt.

Will it still hit 75 without being too buzy? thanx

Nah, it'd probably be plenty buzzy at 75. I didn't have a speedo on my first R though as it was strictly off-road. I imagine on the street 13/48 would get old pretty quick.

Just wondered if 75 was OK in a sand wash or lake bed, 14/48 is OK for 90. :thumbsup:

Your good for 90mph with 14/48?

I just switched back from 15/45 to 15/48, on the road it gets pretty freakin buzzy @ 75mph

Yep, 90 is pretty easy on a lake bed. I probably don't notice the buzz because of my ear plugs.

Compared to my CR250 it lugs like a dream. I've run it up some pretty gnarly rocky sections at Clear Creek without too many complaints. At the top of the Cow trail my bike was cool while the 525 and 300 with me were steaming. I ran 13/46 over the Rubicon this summer and it's night and day compared. I can still hit 70mph with little effort. I think the 13 came with the bike. Can't remember.
