Took it back to the dealer and his mechanic said he managed to tighten up a couple of bolts a LITTLE but on the whole its 100% solid and as new (as expected). It is a LITTLE better..
I did notice that it doesnt ALWAYS vibrate. If i lets say go full throttle from the lights, the vibration sort of comes and goes with a rhythm and if i hit a bump it makes it worse for a half a second.. i think that basically there is nothing wrong and as im used to tiny 125cc single or 1200cc inline fours, this vibration is to be expected from a 320cc single running though a massive rubber band! This is first and only "big" scooter i have ridden, or "bigish" single cylinder. all my other 250cc+ bikes were twin or 4 cyl. I didnt ride a 300i yet, when the dealer gets some more stock of 300/350 i will go and try one
Its a bit like a guitar, when u strum it the whole thing vibrates and if u get the right note to match the resonance of the wood, it vibrates a lot more. I think then that the belt, which is thick and pretty hefty lump of rubber, is simply vibrating as normal and when i hit the natural resonance of the belt or a bump knocks it, it simple transmits more vibes to the rest of the bike.
The vibes are a high frequency not like a jackhammer so its not THAT bad at all really, im just being picky
... They call big singles "thumpers" for a reason i suppose
The actual scooter is awesome though, i can get from 0 to very illegal speeds in seconds and apart from looking amazing its sooooo comfy. I guess the 300 is quite similar (i never tried one).
I swapped a 125 super 8 and a Suzuki bandit 1200 to get this 350i. The 125 was too slow, and the bandit was too fast for this little island i live on (Malta) .. there is no roads here for a 1200cc monster and it just did burnouts everywhere. The 350 is pretty much the perfect balance of scooter nimbleness, and big bike power. It has MPG computer and other awesome gadgets, LCD Display and ABS and the list goes on. Im sure you 300cc owners got the same feeling when u got yours. If you are going to buy one and are thinking about it... stop thinking and get one! amazing scoot!
