Today, the third generation RR4T models are equipped with our own engine made in Rignano Sull’Arno and arrive on the market as the result of a continuous development for many different riding abilities. Many are the refinements and innovations, both on the frame and the engine, all designed to increase reliability and riding feeling. A wide range of displacements are now available, strengthened by the new 350cc engine, a first for Beta in the enduro market. For 2012 Beta has developed a complete range of enduro bikes to appeal to both the weekend hobbyist as well as the seasoned Pro. Engine:
* Redesigned cylinder head including reinforced camshaft bridge, valve retainers, and updated cam chain tensioner to help reduce engine noise.
* New clutch primary gear and springs for better engagement and clutch action.
* Updated counterbalance bearings for increased reliability.
* Stronger cam chain guides
* Increased oil volume to the engine cam chain for reduced friction.
* New oil drain plug for easier oil changes.
Chassis:
* All new Sachs 48mm fork with TFX technology, developed by Sachs exclusively for Beta. This new design allows the fork to move through its stroke with very little friction.
* New SKF fork seals and wipers with self-lubricating compounds to also reduce stiction.
* New triple clamp to match perfectly with the new front fork.
* Redesigned frame with extra gussets as well as an increased tube diameter on the lower tubes. This new frame has less flex and has improved stability.
* New front and rear brake rotors.
* New Brembo clutch master cylinder for a better clutch feel and engagement.
* Redesigned muffler (Spark Arrestor) offers better flow while retaining a quiet exhaust note.
* Redesigned front headlight and front fender support
