Rocker 21 inch rear wheel
Anyone that have tried to fit a 21 inch 260 rear wheel to a Rocker ? I know the 260 will fit an OEM swingarm but not sure about the 21 inch rim. Will for sure not use the OEM rear fender. Have seen that Thunderbike in Germany have made some builds with 21 inch rear and 23 inch front wheel and just love it. It seems from the pics I`ve seen that they have been using an OEM swingarm but want to check the forum and see if anybody have any experience by doing the same changes, pictures of any upgrade would be great....
So, can I fit a 21 inch rear tire to an OEM rocker swingarm ?

I wonder if this might change the engineering of the bike and affect it's handling. I put a 260 on my rim and I haven't liked it as well as the 240 previously on it. I know many who do this and really like the results, but I don't like it as well.

The original tyre of the rocker is 240/40/18R .
You can install without problem the 260/40/18R , because are equivalent and it´s not necessary recalibrate speedo.
If you want install a 21", you must install an equivalent tyre. And the tyre equivalent is 260 or 240 / 25/21R(not typical size of tyre) .This is to maintain manufacturing measures and dont have problem with the swing arm and the rear fender.
If you want install 21" with other sizes and not equivalent tyre , you will do modifications in the bike.
