'87 CR125 Rear Rim Size

[Wanna_Torque_About_It?]

Hi everyone, I've been slowly rebuildin an '87 Cr125 and have had trouble finding new 18" gold spokes for the 18" rim, I can however easily find 19" rims and spokes. Any upside/downside of changing rim sizes? Anything I should be careful of? Thanks.

no downside to it.

Any loss on suspension travel?

Not sure why you'd think there would be any loss in suspension travel, 18" rims and tires still have about the same outer diameter as a 19" rim and tire.

No because the tire size compensates for it.  the 18" wheel has more sidewall on the tire than the 19" wheel but the total circumference is the same.  Similar to if you put larger wheels on a car.  You get a lower profile tire to compensate and end up with the same circumference on the combo.

Ah,that car reference made me understand this much more. Thanks, and I'm learning new things all the time. Thanks for your help everyone. 19" rims here I come.
