Stock is 13/42 or 43.

I ran my buddy's with 13/46 and it made quite a bit of difference. He was faster than me flat out too. I simply can't maintain speed in 6th and always have to drop to 5th to maintain R's.

My concern is once I change the gearing, the speedo will be off. You can get a speedo healer, but I've yet to find one under $100.

Oh ok, so the front is already good. That's good to know. Just need to buy a 47 then I guess.

Also a larger chain. As far as I know, stock is 108, you'll need 110. Somebody correct me if I'm wrong.

Has anyone had experience with the moose racing plastic skid plate? I run an aluminum skid now in very rocky terrain and it holds up and works well however I have to pound it out after every ride and its noisy. Will the moose hold up to this type of terrain?

Ok thanks. I'll probably just buy one of the kits with all three at some point. Ebay has them for around $114. Dunno if that's good or not.

I'm not really doing it for top end. Mainly for low end for me to get it a little better gearing in the woods. I also have no problem with top end. Can hit 104 on the speedo, I assume probably around 92ish GPS.

Also, just installed hand guards so I'll whore a pic. Have had her almost a year at this point. 2012 I picked up for $3500 last December.

13/47...

...Is pretty much equivalent to a 12 front and stock 43 rear on the WR-R.

I tried that first (cheaper to buy one sprocket), but next time I looked the rubber swing arm guard was chewed almost thru. Changed to 13/47 and 112L chain at 12K miles and all has been good since. Bike is pushing 25K miles.

Unfortunately you are the first person I have heard of that is getting those numbers in stock form. You must weigh about 130 lbs too. At 230lbs I need the lower gearing, not for top speed, but for low end trail riding, and maintaining a 70 to 72 mph cruising speed in 6th.

Regardless, on a 250cc bike, real top end is a sort of usable benchmark for overall performance when used in conjunction with low end and cruising speed. It's not like we are on 1L bikes or hyabusa's where top speed = death wish, near 200mph performance. In my mind (for any bike) performance past 120 mph on the road is totally superfluous... 120mph is probably a bit high too.

If you have a 1/4" aluminum skid plate and have to pound it out after every ride there's NO WAY a plastic one is going to survive. For the noise, just put some pieces of rubber between the frame rails and the plate. Also it will allow water to drain so you don't get premature frame rust.

This.

I just did 105 miles of trails yesterday and my top speed of the day GPS verified was 74.1mph with stock gearing. It also was in 5th gear. With stock gearing, maintaing 70+mph in 6th will be tough. 6th has ZERO pull.

I'm not saying 97mph isn't possible with stock gearing, but I am saying I'd need a ship sail attached to my back and be going down a hill to get it.

I'll be going to 13/46 or 13/47. It appears that they don't make 46t rears anymore, so I'll be leaning toward 47. If I don't like it and it kills my top speed too much, hopefully I can throw on a 14T front.

Mine is stock throughout the powertrain. I have no problem pulling the 70's and my top speed is about 90 at lower altitudes and in flat conditions. But yes, any grades get me downshifting to maintain my speed. I like to settle in just off the throttle stop.

I think the Colorado rider stretched the truth, though. Mine won't pull 90mph at the 6 or 7k altitudes I found in CO/WY/UT.
