Yes, the new Engine is loosely based on a Yamaha design but it is not quite as parts interchangeability compatible as the old 230cc Engine was that was Honda CG based. Also, the new engine while is a 249cc rather than the old 229cc ,is also 7 pounds heavier . Joe Henner of Joe Henner MotorSports who is known as THE " RXB Guy" has already identified some mods /parts for the new engine and has them on hand.They are not as numerous as for the old style Engine but there is still quite a few , such as 4 degree advanced timing key, CDI box ,and a few other pieces .The frame and suspension remain the same so he can also upgrade the rear shock .,etc. The RXB Owners Group FaceBook page has a lot more info and details . The " old" RXB 250L is a very capable off road bike that performs better than anything else in its class in it's price range in the dirt ,the Brozz 250 and Hawk DLX might be better on the Street side of things, so it all comes down to what your primary use is going to be . Personally i was a fan of the "old" style engine but ORION didn't really have a choice on going with the new engine because ZongShen said they were no longer going to build the 229cc.I'm sure the 249 will be reliable and durable ,the only drawback to it at this time is not as many aftermarket hop up parts.But , i am confident they will come in time, the big issue is the 7 pound weight increase but unless you are really thrashing i dont think it will hurt the average trail Rider .
