so.... i jumped the gun and ordered 2 different anti-vibration devices.
this is currently sitting at point bob waiting to get picked up... and i got no use for it.
80 canadian shekels and you can get rid of a bunch of annoying hand numbing vibrations.
they also look cool.
like to af1 store and their price (without shipping)
not sure if it will fit tv4. can try.
if that picture is correct, i did a quick cross referencing on parts and it might fit the following bikes as well
11-'13 Tuono V4, '03 Mille, '02-'05 Tuono, '06-'10 Tuono, '04-'09 RSVR, RSVR Factory, '11 Shiver, '08-'13 Shiver, '08-'13 Mana, Mana GT
*might* so can meet for a fitting.
