The 2013 MY Beta 450RS features a new Sachs 48mm fork with TFX technology which provides more precise movement with less friction, thus improving the feel and increasing the suspension performance. This new fork has been designed especially for Beta machinery. In this regard, the fork seals and wipers have been replaced with ones that have self-lubricating compounds, and a new triple clamp has been fitted to match the new fork.
The frame has received an upgrade also, with extra gussets and bigger diameter lower tubes, which make it flex less and and improves the overall stability of the two-wheeler, both during sharp turns and in fast straight lines.
