Hi,

I can't seem to find a thread with the information i am after. Maybe someone can point me in the correct direction if there is already something out there. If not possibly i could get an answer.
Just wanting to check to see what is the biggest tyre that will fit on the rear of a 2020 KLX250s (Aus). My current Shinko on the back is 120/80 and i think the nobbies i were supplied when purchasing second hand are 120/100 (will need to confirm when i get home)

As i am getting the nobbies put on this weekend for a trip to a mates property and im concerned that i might have issues putting them on with the bigger size.

Any info or help would be greatly appreciated.

 

There's a lot of tire info if you do a search. Why would you want to go larger?

 

I don't want to go bigger, just want to know if the current nobbies that I was supplied with the bike will fit. I am sure they were on the bike when I checked it out, but asked the original owner to put the stock ones back on due to my main use.

 

Gotcha! I'm still running the stock ones off road, and just mounted 110/140 for the street.

 

I looked up the tire sizes for the KLX300R from 2020, which is very likely using nearly the exact same swing arm since the frames are extremely close to the same minus a few brackets. Then I looked at the tires the 300 had, since, as an off road bike, it would be running knobbies. The 300 runs a 100/100-18 rear and an 80/100-21 front tire. So I'd say stick with what they run. You don't need the widest thing you can stick back there, because that would just be heavier, taking up more power to run and more likely to bog down in mud and sand. Smaller lower powered bikes always benefit from a narrower tire. I run a 4.10-18 on the back of my 250 instead of a 120;80 because it is lighter, takes less power to work, I can break it loose if I need to, and it's $20 lower cost.

 

In case anyone else wants to know the 120/100 do fit.
