Hello Gentlemen,
Am looking at a 2013 GRiSO & just want to verify the beginning years that rollers came from factory.
Thanks,Philip

Mid 2012..but numbers are rubbery. A 2013 should have rollers, but I would not be surprised if a flattie snuck through very early.

2013 you should be safe. I've never heard of a '13 plated flat tappet bike but certainly the factory's engine numbers for the swap are a bit rubbery and I've seen a couple of bikes with engine numbers supposedly post change over that still had flatties but they were 2012 models, just with later engine numbers.
