Used to run the Wr 15-50 with 89 on the gps topspeed . Im looking to do a maximum of 100mph - nothing more.

Would 15-45 be suitable? or should I look at a 48?

Just want to cruise 70mph on the highway without stressing the motor out!

I just went from 13/50, (stock on the 07-09), to 14/50 for my first DS ride...

I still ride A LOT of single track and I think I could still drop a tooth or two off the rear and keep a decent first gear.

The 14/50 allowed me a 45-50mph cruising RPM in 5th gear but I would like to cruise at 60 if I could and still be able to navigate tight technical stuff. I still race my plated bike in our local off road series:thumbsup:

I wanna hear from someone with a 07' with a 15T first... the primary gearing is taller than the 06' or older already and I had to tool out the case saver just to get the 14T on there... I think the 15T would run the chain dangerously close to the case...

I think going to the 14T for me was the equivalent of you going to the 15T.. I hit 89 with the speedo no problem last weekend but it's ready to bounce off the rev limiter... I am thinking 14/48:ride:

speedo's arent that accurate... 89 on the gps saw me at nearly 100 on the speedo.

are you certain the primary is higher?

Fairly certain but that's only based on seat of the pants feel and the fact that I had always dropped from a 14 to a 13 on my steel framed WR's and it felt lower than the 07' stock... but to tjhat point, I did try a 12T on my 07' and it was WAY to short....

I did run a 15T on my 04' for the Desert races and it worked well... I could not tell you what my top speed was but it had some top end. That was 15/50

I just swapped the front from 14T to a 15T on my 03'. Has improved the speed in 5thgear by about 15klm/h .

Yes 07 onwards has a higher primary and hence uses a 13t.

You won't get 100mph going 15/48, - 15/45 more likely but that is quite a jump. OK if you are mainly road use.

I use 15-50 on an '06, I would like a taller 5th for road but off-road the gearing is still usefully low enough so staying as it is for now...

would the 15-45 be too tall for any offroad work?

Don you are correct.

Having had both an 06 and now an 08, I think the best overall dual sport/desert gearing is 14/50 (for an 08) and 15/50(for a pre 07)

I have tried the 15/48 on my 06 and while it did pull the gearing up top to about 98mph, I found that I had to wind it out pretty good in the tight stuff. It was nice on the long rides and for cursing. I guess it really depends on what your looking for...

Tight stuff yes...open stuff no

I think i might go with the 15-45 for gravel roads and jeep trails - also get the 12-13-14 counter shaft sprocket to make things abit easier on the technical rides.


after all the 3 countershaft sprockets cost about the same as 1 rear sprocket.


what you guys think?

I know there are some trails around here i need 14/50 to get up the steep rutted hills etc .
