This is my set up
Same effect as driving in the right gear.
With the stock gear ratio 15/39, riding the 1199 was "almost" like driving in 3rd when you should be in 2nd. Not quite that bad, but definitely noticeable when the rpms are below 3k.
Changing the rear sprocket to 41t, makes the FDR just right for the superquadro.
Is it possible to upgrade to a 41 tooth rear without changing anything else? Will the stock chain fit?
No . You need a new chain is the best advice . If you must you can but the rear sprocket runs very close to touching the swing arm .
hmmm, I guess the question is, do I go with the whole 520 conversion thing....
Is adding an extra link to the stock chain not an option?
What special tools are required for installing a new chain?
Hopefully my final question! Is a new map required after the change???
