06 wr450 sprocket question

6 posts in this topic

Hey all I have a 06 wr450 sumo and have recently decided to see about changing up the sprockets so I can get a better highway rider. When I ride I will be riding highway that's 50 miles + and also want to keep it in the 75mph range without revving the hell out of the bike. Currently I have 14/41 sprockets. Is there any better setup to get the revs down on highway speeds?

thanks

Go to a 15t front sprocket.

I have 14/40 on my sumo and it's ok on the freeway, I wouldn't want to do sustained 75 though. Obviously your 15/41 is significantly taller.

 

You can get rear sprockets as small as 36. That would help a reasonable amount (if you have the power to pull it - I haven't tried that). I don't know that any larger than 15 will fit up front, though. You'd probably have some issues with the chain guide, I can't say for sure.

Don't think any bigger will fit up front but will say 15/36 make it so slow getting to speed and will it even do in the 70s at that gearing? I'm not worried about power it's got plenty I believe.

Yes, it'll certainly slow it down at lower speed. I think 36 would be excessive, but I'd consider trying 39 or something and seeing how you like it. I don't think it's possible to have a WR that does well at low speed and at 75, so you need to decide where you want to compromise.
