Subject: AT history (XLV, NXR, XRV)
Hi Jorn and all others,
I've never heard nor seen the XLV 750. May be it was never imported in
Belgium ! I suppose that you're talking about the secondary transmission
when refering to shaft/chain drive ? In your previous mail, I thought you
were talking about the way the camshaft was driven !
As far as I know the whole X(L/R)V family shares the same engine basis. It
was easy for Honda to change the three-valves head to a four-one for the
NXR. Maybe we only got three valves because increasing the number of
valves usually means more power at hi revs, but less torque in low revs.
As it's obvious that Honda did not meant to make the AT powerful. This may
be the reason for loosing one valve ? Also, more torque at low revs means
a bike easier to handle.
Now a question Jorn, what do you now about other similarities/differences
between the XRV/NXR (frame/suspension/brakes ...) ?
Pierre
