- Today on JD Cars we’re regearing my 2017 WR250R from 13/43 stock gearing to a more off-road oriented 13/49 gearing setup. I chose to go with a SuperSprox 49T Steel rear sprocket as opposed to aluminum. The aluminum ones are nominally lighter and wear out more quickly. Overall, super satisfied with the 49T rear sprocket and 13T front sprocket. She putts along at idle around 3mph. This gearing is a nice combo setup. You can do some slow technical riding in the sticks, but you can also still open her up to ~70mph on the street.

I bought my used WR250R with all the usual mods already done, including 13/49 gearing… way too low for town traffic use IMO, first gear becomes redundant !
I then changed to 13/45, I thought that might have been the Goldilocks size, but I still found that too low, returned to stock 13/43 a couple of days ago and I like it best, still pulls away plenty zippy. Don’t forget these little guys love to be revved !
Ive got a 20 wr with a few mods and also gps adjusted speed healer. I’m 13/48. 70 mph is about all I feel comfortable cruising at. Very comfortable at 60-65 though.
Nice! What other mods? With corrected speedometer (using Speedo DRD), I'm cruising at about 55 mph... anymore and I feel bad for pushing the RPMs high.
Contemplating a set of street wheels, tires, and gearing...
You can change your own rubber. Quality aftermarket front sprockets(like your rear) are fine. Nice vid!
Thanks man!
I’m going opposite direction I think I want to see if I can get 100 mph on it.
Or a Ton like the old British dudes.
Kinda neat for a 250 I think.
Just a Top Gear Top Tip, the WR250R and WR250F are COMPLETLY different bikes. They share no components with each other.
Good to know 😂
That's not true. They have the same oil filler cap.
I have 13/49 on mine as well, never rode stock but I love the 49 rear. Still cruises on highway just fine at 55.
Whate the top speed man ? ( have u got speedohealer? )
@@_davidsuciu around 87 yes I do
@@KevDoesStuff 87? I'm running 13/48 and can barely do 60!
@@maxdaddy6434 that doesn’t seem right at all. Something must be wrong lol
@@KevDoesStuff 85 is about the stock top speed so 87 after a 49 tooth mod which decreases top speed doesn’t sound quite right.
Hey its the dude from the taco camper channel! I bought this bike after watching some of your videos! Have you stuck with the same gearing and tires. I need to replace mine on the new (2008) WR250R.
I might have missed it, what length of chain did you go with? In the vid it looks like your chain tension adjustment is pretty far out like your not going to have room to tighten the chain as it stretches out. Im about to do this mod, gonna go 13/49 and i think i need a 110 chain.
110 sounds about right. I had to shorten the 120 link chain by about 10 links or so.
112 link is what you want
Noice can u put links for cheaper f30 bumper n parts
What websight did you find that chart at? The ones I found just show ratios not speed
www.blocklayer.com/rpm-gear-bikes.aspx
here's one not sure if its the one he used
Can please send link for purchase?
I have a stock 19 so if i want lower rpm highway speed do i need to go 14 front? Im not sure what stock is i think 13/48? Im riding 99% highway. Thanks.
See I was kinda going the opposite direction I’m wanting to make a ton on it.
What was the name of the calculator you used would be really help
Thanks for asking! Here's the site: www.gearingcommander.com/
Be careful with aftermarket front sprockets, CycleCruza used an aftermarket front and stripped his splines out and he had to get the cases spilt.
Not sure if was install error or what, just a headsup.
The new sprockets CycleCruza used after he repaired that problem were the same brand used in this video. Supersprox
I have this on my WR as well. Soooo much better offroad. With the stock gearing 1st is still too twitchy offroad but 2nd gear puts the motor too low in the rev range and it fuckin HATES lugging. Yeah it's doing 8000rpm at 65 but....oh well.
Can you tell me what is the chain size links ?
The stock chain used is a 520 x 108. If you install a larger rear sprocket, it will be a few links longer.
I would have went 14 49
Thats the setup i wanna go , but unlike him , i ride 70% onroad
