I have bit the bullet and gone for a 21 V4 SP after owning my 899 for 10 years. I go to the TT most years and have the SW Motech Blaze pannier set for the 899, question is can I buy the brackets to adapt these to fit the V4? I see they are listed for a V4 street fighter but not the Panigale! Are they not the same subframe and seat unit?? Any other options to consider?
I go to the TT every year and having spent >10 years with the same issue (luggage) I now ship my stuff the week before and travel with a rucksack and minimal stuff. WAY easier and only costs about £20 for the service.
