Sprocket sizes

[Hennie]

Hi all,i am new to this site,just bought my 1st AT(very happy).
Can anyone tell me what the standerd sprocket sizes is for a
D07.
My AT is running 5200rpm at 120km/h.Is this normal?

Dit anyone try a smaller back sprocket yet/what will the pros/cons be?

The standard rear sprocket is 45 teeth. I've just replaced mine with a 43 tooth one. This has dropped the RPM at 70mph from around 5,000 to 4,700 - not a huge difference but it does make it feel a bit more relaxed at motorway speeds.

Does that reduce the "vibes" by any chance.... I get a real problem with my right hand goind numb at certain speeds...

and also.... does it alter two-up touring comfort/abilities in any way?

I have been running a 43 rear for a couple of years now.
It does not feel any different pulling from a stand still, where it seems better is at motorway speeds, a more relaxed feel and the roll on from 75-80mph is much improved. In theory the standard gearing should pull better but i think it is in a sweeter spot in the engine revs.
Or is it just my imagination.
