Hi All.
i want to change the front wheel on my RK custom to an 18" one but i,m really happy with the ride height at the moment (i,m only 5' 6" tall).
Can anyone tell me what the overall diameter is of an 18" front wheel please with tires on ?

I have measured my stock 16" wheels/tires and they are 24" in total diameter.

Thanks.

Just go to the tire manufacturers website i.e. metzlermoto.com, they all list the mounted diameter of the tire. For an 18" wheel it would likely be a 140/70 18 vs the 130/90-16 so the height difference is minimized by the reduction in sidewall height 70% of the overall vs 90% on the stock.

 

09 SG here so the front had 17inch Dunlop I chose AVON Cobras, again check the mfg websites for exact dimensions, that's where I got em.

17 Stock Dunlop = 25.20 Overall Diameter
18 Avon Cobra = 25.50 a whopping difference of .30" <G>

130/70 18

 

Hi,
I,ve been on both avon and metzeler sites and cannot find anything that tells me the overall wheel/tire diameter.
Can you post the link please.

Thanks.
Rowle.
