I wanted to order up some chain/sprockets for our bikes today but don't know what we have on there right now. Red's got stock on his 450 and I have one tooth bigger on the rear on my 250F over stock (never did decide if I liked the one extra tooth better than stock but might as well stick with it).

Anyone know the stock sizes?

According to
http://www.bandcexpress.co.uk/pdfnew/renthaloff.pdf

The YZ250F is 13/48
The CR450F is 13/50

I confirmed the YZ250F gearing here http://www.thumperfaq.com/wrf_vs_yzf_2003.htm#Diff

And the CR450F gearing here http://www.morganhondamotorcycles.com.au/latest.htm

I was researching the info when Thump jumped in with it before I hit the submit button. Otherwise I would not have known what it trully was and would have bypassed the post :)

Glad we could help Nikki.
