running a 110/90-19 on a kx125?

it comes stock with a 100/90-19, but i have an extra rear tire from my 250 laying around, and would love to run it to save money. any negative outcome to this?

lmk thanks! :thumbsup:

I've tried the wider tire setup on my 250. It just doesn't work all that well in my opinion. Too much rear tire just overpowers the front tire in turns and ruins the handling, and the wider front tires ruins the feel of the front end. And on a 125 it will make breaking the rear loose when you need to more difficult. Stock sizes seem to work best to me.

If you want to save some money, go for it. The things Chokey said can happen, but its not like it's going to ruin any rides, it won't be too terribly noticeable.

Hell, my little brothers 125SX came stock with a 2.15" rim and a 110.

I ran a 110 on my 250F, which comes stock with a 100, and I actually liked it more. Now I run a 120 on my 500, but its a 500:busted:

Some tire manufacturer's interpretation of a 100 width vs a 110 vs a 120 is different as well. I have a Dunlop 110 on my 500 which is as wide as the Dunlop 120 that came on my Yammie 450

100 to 110 will not matter too much, but it does add a little bit more rotating mass, which may be noticeable if you are truly riding your bike at the limits, but if not, probably not

thanks guys... i'll run it, worst case scenario is i'll buy a new tire, lol.

Use 100mm tyre becouse it have smaller diameter, and 125 have low torque. With 110 is heavy rich powerrange in all gear.

      Hi all,
      I have a 2004 Kawasaki kx250 that died suddenly on me the other day. all i can get it to do is backfire every once in awhile. Tested the resistance and everything of the magneto and stator with a multi-meter and all is good.  Coil is new oem Kawasaki the reeds are brand new vforce and the top end and carb have been completely rebuilt.  key on crank is intact and all the timing marks are lined up. I hooked a timing light to it and spun the motor over really fast and found that it is sparking way to late.  The service manual says that it is supposed to fire 14 degrees before TDC but it is sparking way after TDC.  Im thinking its a fried CDI box since its the only thing i wasnt able to check.  Any help would be appreciated

      Hi all,
      I have a 2004 kx 250 2 stroke and it wont start.  it only backfires.  I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up.  It only pops or backfires when you kick it.  Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new.  It was running great before so i dont know what happened.  Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking.  Any help would be greatly appreciated

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
