Saw the 331 bike about a week ago , was on mxa as well , frame looks smaller engine more compact , around the oil filter area is a lot different , kickstarter a lot straighter , did not see the clutch side of bike , plastics are new , even the fuel tank different as the cap is at a flatter angle , right side radiator hose is changed, bike had showa suspension on it , I cant see them changing from showa just yet, shock looks to have a different shape to it as well , may be to get around the new frame? Lets hope it a bit lighter as well, herd off another dealer about the 300 direct inj 2 stroke , could be 16 or 17 model , I hope there not pulling my chain , as it would sit nicely with all the green bikes in the shed?
