dwb5151 Posted September 3, 2016 Author Report Share Posted September 3, 2016 Thanks for the info would it be worth while going the extra money for the 300 instead of a 280 Quote Link to comment Share on other sites More sharing options...
barfy Posted September 4, 2016 Report Share Posted September 4, 2016 I went for a 280 rather than a 300 because someone said to me that 300s had overheating problems. It was due to the boring being so close to the water ducts, it could be helped by fitting a larger radiator. That's probably why the 300RR achieves the extra capacity by a longer stroke, which is also described on the excellent Montesa website (http://www.montesa4rt.nl/).
