110 or 120 on the KX5?

[Polar-Bus]

I seem to be getting some conflicting info on exactly what size rear tire is supposed to be on my '01. The .pdf kawi spec sheet calls for a 100 ?  (I seriously doubt that). There is a 120 on my bike now. I thought they cam std with a 110? What do you guys prefer? Has anyone experimented with different sizes?

110 to my knowledge was stock. 120 is my preference.  100 is too small.

I ran  140/100X18, great tire but heavy turning on the track. I prefer a 110 on the MX track.

agreed. I am thinking of stepping down to a 110 with a lower aspect ratio. I still have some front end headshake, and I think a lower profile rear will rid the bike of this frustrating occurance. Your not really going to have a "berm railing" machine with a KX500 anyway, so I am going for a more stable high speed handleing type of machine.

My KX used to rail berms like nobodys business. That was waaay before I started dumping in the big bucks. Also, you will never have good stabilazation unless you get a steering stabilizer. That is an absolute must if you are looking for top speed runs.

You need to spend a day with the new KX450F (I did). You will throw your 500 in the trash.

KX500's still have their solid purpose in off road, but as for the KX500, IMO, its NOT in the berms. Bottom line you just simply can't easily transition foreward on the seat.

as for your steering stabilizer, you are probably right, it might come down to purchasing one. I have gotton TONS of nothing but positive feedback on stabilizers. Heck, I even know a few MX guys that run them!
