No throttle means no lubrication. I don't think it would matter though unless you were engine braking for a very long time, like dowm a very long hill. Any 2 stroke experts on here? |

Re: Engine braking... any hazzards engine wise?
So long as you downshift smoothly then there's not a problem, why would it wear the clutch out, if the engines slowing you down then the clutch is engaged.
Just don't crunch through the box like a monkey, it should slip in when you blip it to the right revs Also a 2 stroke still has lube at idle, if it's got an injector pump then it'll still feed it oil.

RE the RS125, yes. It's not recommended to coast on the over run on 2 strokes as there's no lubrication for the mains and bore. Manufacturers advise keeping the throttle open partway.

Re: Engine braking... any hazzards engine wise?
there is a problem with this. If you down shift too early to the point that the engine revs very high then you can cause serious damage. Remember that the rev limiter only works by inhibiting ignition and so offers no protection at all if the engine is mechanically driven too fast by the back wheel.
Provided that you keep the revs within a sensible limit doing this then you should be fine. I have seen a bike on track spew its guts out as a result of very high revs in a downshift though. |

Re: Engine braking... any hazzards engine wise?
There's very little extra wear on the chain and no extra wear on the engine/clutch/gearbox. You wouldn't notice a single penny of savings by not using engine breaking.

Partially true,but as long as you keep downshifting at a reasonable rate(not easy,it feels great!!) and as long as you don't cause overreving due to downshifting,you will never replace an engine part because of wear/damage caused from downshifting |

Just keep an eye out for Sheriff Rosco Coltrane...
Other than that you should be fine
