Any "issues" with a 50T rear sprocket?
I know. I know. There are dozens of threads about rear sprockets and gearing on the KLX250S posted here, and I've read most of them. Sorry.
I still have not seen much on the 14-50 sprocket combinations, however. I currently am running a 13-47 set up and am very pleased with it. I accept the top end limitations in exchange for single track gruntability. I figure a 14-50 combo is within a half tooth of the 13-47 I'm running, and am on the verge of a new chain, so will probably change the sprockets too. It just seems like the 14T would be better for the chain's life and maybe just fit better. Question is: Are there reasons that I should not use a 50T on the KLX? I do realize it would be slightly heavier since all components are larger, including the chain. |
It's exactly what I did on my '06. I ran the 13/47 setup with excellent results. When I decided to install a new chain just before my annual Utah trip in May, I went with the 14/50 setup. I wanted a larger front to ease chain stress at the countershaft, and the 14/50 is the same as the KLX300 and yields basically the same gear setup as the 13/47. Even with the 13/47 I had to mod my rear chain guide to allow for the bigger rear sprocket. It isn't hard to do, as you just reorient the guide in the rear mounts. I only use two of the three mounts on the swingarm...the two forward holes...and adjusted the angle. I've had no issues with that modification. You just have to get creative.
I agree on the lower gearing being way more useful off road. I'd hate this bike without the 13/47 or 14/50 gear for my adventures. I limit myself to about 55 mph for longer pavement sections. I do as little pavement as necessary, but on my trips out west, I have to do a little pavement from camp or back to camp in many scenarios. I would avoid interstates at all cost.:D I'd also add that I now use a Hot Foot Moto rear guide and front rub blocks and used part of the stock aluminum rear guide plates for my setup. |
Thanks for the input. This just the kind of information I was looking for. Your type of riding sounds just like what I prefer.
I'll take a look at the chain guide business to see what I might need to do. I bought my '06 used with the 47 already installed, so if I had a problem with the guide I didn't know it. I checked out the hot foot stuff too, but if I understood you correctly, you had to modify your rear guide anyway, even with the hot foot. |
I ran a 49 tooth rear for a while and want to put it back on. I now have a 45 and its just too tall for my riding. The teeth would rub a little on the chain guide when I was pulling the rear wheel or dropping the chain off to change the front sprocket (13, 14 & 15). I just let the teeth rub while doing this and it chewed a little of the chain guide away. No problem.
Also picked up a Hotfoot Moto chain guide and swingarm wear piece. I used the chain guide all on its own without a problem. The stock aluminum one took a bad beating and was unusable. Thad can explain why he used the hotfoot part AND the stock one together, but I'm not sure its necessary to take this approach. |
It really is the best gear for off-road, IMHO. It really allows the bike to move in the powerband on the trail.
I just went back to a semi-stock 14-43 and it is really lacking on the trails. I actually slipped the clutch today, something I never did with the 13-47. But I'm no longer looking for 7th gear on the road. I agree that more chain on bigger sprockets will give more life for the drivetrain. Where did you guys find the 50T? |

Thanks Matt!
I never remember to check that site. |

Somewhere on this forum, someone said the largest size rear sprocket that would fit the chain guard. I think it was 48, but not positive. I don't think it worked with my 49.
I think this is the thread https://www.kawasakiforums.com/forum...existant-7615/ |
