125-200cc Late WR125 came with what tyres when new?

Just bought a 2009 WR125 and have some Michelin Comp vi tyres in 140/80/18 + 90/100/21 that I had bought for my gas gas. Wondering if they are the best tyre size for this bike. Bear in mind the Michelin's quirky measuring method means the tyre is comparable to 120/90/18. I think this is right anyway!

My2013 wr125 came with michelin enduro competition 111 size 120/90-18 rear, competition ms size 90/90-21 front.
Hope this helps you.

Thanks very much. I just bought an 09 with three previous owners and it had exactly these tyres on.

Are you still using these?

I'm still using the original rear. Idid try a dunlop 606 I had in the shed but wasn't happy. I went back to the michelin as its not worn out yet.
I'm using a motoz tractionator st on the front, mainly due to the type of terrain I ride which is dry, powdery and rocky - typical South Australia.
When the rears worn out I'll look at a motoz replacement - Gotta support local companies.
