Aimo,
I have not tried it so I can't swear to it ... I am not currently aware
of anyone who has ... However ... the drive axle in the transmission is the
same part number for the Vmax and the Royal Star. The main axle in the
transmission is a different part number but the Royal has 16 teeth,
(machined onto this shaft), and I suspect this is the difference.
I haven't heard any of the "not able to cope" chatter about this
modification. The Royal Star makes the same torque at 4K RPM as a Vmax does
at 6K, (the Venture engine makes more). The Royal Star weighs 100 lbs more
than a Vmax, (the Venture weighs more).
As you can see ... the drive axle in the transmission is the same part
number ... the middle gear set is exactly the same part number; the drive
shaft is a different part number but it is 1 1/2 inches longer than a Vmax;
the rear axle is the same part number and of course the rear end is the same
unit but with the 10 tooth pinion, (which I think comes on European Vmaxes
anyhow .. and of course the Royal/Venture has the hole drilled for the speed
sensor ... that somebody I know is going to use to drive his SPA combo
tach/speedo).
There are differences of course ... like the clutch basket, (which has
a different number of teeth machined onto it and changes the primary drive
ratio .. and has to mate with the correct crank gear etc), but I don't think
durability is an issue here .... (the Royal/Venture has a five year warranty
period and it is bigger).
However .......... it would be cool to hear what Eiffelmax is offering
... I am suggesting that if they are selling a 21/28 tooth gear set
that they might be selling Royal/Venture gears ......... Since they
"have" done this ... it would be interesting to see what you could "squeeze"
out of them ... ;>)

replacement 5th gear sets
Will they fit the Vmax? I heard stories of not fitting
or not able to cope with the Vmax engine power
output.
