September 23, 20178 yr They've been like that for at least a year if not more judging from the betas I've noticed recently. Guess they decided to lengthen it and not bother changing the pipe.

October 25, 20178 yr I see on the Beta website they say the 2018 has ‘larger oil pump for decreased engine brakeing’. hmmm- I seem to have trouble imagining how a larger oil pump descreases engine braking? Does it really work? or is the ‘twin spark control’ actually do more? Or is it all just hype.

October 26, 20178 yr out of curiosity, I did look up the part numbers for the 2016 and 2018. there is a change in number for the oil pump. I'm still not sure how that would help engine braking. I suspect sales staff not knowing, and perhaps the new 'twin spark' CDI making the change? Since I've been riding 2-strokes for years and like the minimal engine braking, I am interested. Mark
October 27, 20178 yr Funny, most 4t riders like the braking. Otherwise they would buy the 2 stroke. Reality is all 4 strokes are big and heavy. But my son at almost 6 foot 5 loves the 4t the way it is and will be buying a 2018 factory if they don't change it much.

January 16, 20188 yr This is what I found about twin spark at Leonelli site. Seems like an effort to burn all the fuel on the chamber.

NOT!
