Expensive super dynamic Prop
Spoke to someone today at AB Performance who was very helpful and had lots of useful info.
One thing he insisted on his bec was this prop which i forgot exactly what it did but he said anything other than these makes bec's undrivable
.
The prop as far as i remember was a prop inside a prop, which made accelaration and decelleration smoother.
Can anyone enlighten me with there experience !
Oh and it cost about £400 ouch ...

The prop to which you're referring to is a TRT Prop or Torque Resilient Tube. It is indeed a tube within a tube down it's whole length
joined by what can be described as a cushion of Polyurethane, Rubber etc etc. This provides a natural cushioning action of the engine force to the
driven wheels through the rubber. When you adapt the engine of a bike to a car you remove the cushioning included in the rear wheel hub. The TRT
basially put's it back.
The price of £400 is very steep - there are a few guys on here who have purchased them for figures circa £200 - it pays to shop around. Avoneer knows
a good cheap supplier of TRT's. Drop him a U2U I'm sure he won't mind.

My TRT came from MNR via dunham haines <SP> and was £295 for both front and rear prop... (via quaiffe box)

TRT is a nicety rather than a necessity, it just helps to make the driveline less clunky. I managed without one and had no problems, you just have to
perfect your gearchange a bit more....
If starting from scratch its good to get one if you can. On my first built I was ignorant of the option

What provides this cushioning when using the Complete Sierra drivetrain?
In the sierra the prop connects onto a big rubber "doughnut" but this has to be removed and repleced with a knuckle joint for the prop to
fit into the transmission tunnel.
By removing this has the cush also gone out of the sierra drivetrain or is there still adequate cush elsewhere?

mhh
i just let it be there..
i have now hooked that rubber thing up to my Diff...
i made an ring wich centers on the diff flange.. in this way i managed to bolt the thing up to the diff, in order to keep something of rubber in the
train.
the only thing i shortened was the sliding part......
Works nice, only an bling when selectig first gear...
Tks

Sierras dont use dog clutch gearboxes so its not needed...
Bike gearboxes are temperamental, especially kwaks and yams, with those motors I wouldn't go without a TRT..

Oops, forgot about this thread lol
I understand it stops bike boxes self destructing, was just considering why when used in car form we can simply do without.
I know these cars are about feel etc but I think it maybe makes ours feel a little jerky under engine braking etc as we've maybe removed some of
the "give" in the drivetrain.
Anybody else noticed anything similar or any thoughts on the matter?
