BETA RR 4T FINALLY ARRIVES



















The new Beta 450 enduro bike has finally landed in perth. This years bike is 100% Beta! Over the last few years Beta have been using Ktm engines to kickstart their enduro project, but after years of development they have finally their released their new engine in the 2010 range.
The current market is very competitive so Beta have not only focused on getting the bike quick, a lot of there design has been targeted on reliability. The good old days checking your oil once a year and "what is valve clearance?" are gone. Beta have designed the valve train with this target in mind, They have used a finger follower with a low friction DLC coating (Diamond Like Carbon) to provide high stiffness and a low oscillating mass. The oscillating mass of the finger follower system with steel valves is nearly equal to a tappet style valve train with titanium valves. This means upper limit of the valve train is over 12000 rpm. Due to the low oscillating mass, high stiffness of the valve train and the selection of materials and coatings, the cylinder head is practically maintenance free.

















The new engine also uses 2 seperate oil circuits, one for the top end ( crankshaft, piston, cylinder head ) and the other for the clutch and gearbox. This is beneficial for two main reason, firstly you can use specialized oil for engine and clutch and secondly the wear from your clutch plates wont contaminate your engine oil.

If anyone would like more information or a test ride on the new bikes don't hesitate to contact us.
