You are very close. 255 to 260 with armour and rad guards is about right. I checked the magazine articles when everyone was dogging GasGas b/c the Betas were supposed to be "feathers". That was only way that Beta advocates could attack the GasGas machines, There was nothing else that they could argue. The Betas with a full tank of fuel are 252 pounds. I checked all the articles listing weight over a one year period and this is correct. Someone can say its wrong, but you need to show me objective evidence not unsubtantiated claims. Make sure to specify where this miracle weight loss on the Beta occurs. i.e frame, engine etc.The Gassers are about 8 pounds more per the magazines(except Dirt Rider whose claims that the GASGAS weight was 274 pounds and that the 300 ENGINE GASGAS WAS DOWN ON POWER were so stupid and outlandish that they lost all their credibility.) GasGas is cutting some weight off the 2014s at the engine, frame and wheels which should put it around the Beta.
