Title: V85TT variable timing vs static
Post by: th_01 on May 09, 2025, 12:31:36 PM

Hi All


Any V85TT OWNERS with the new variable timing motor ?   Do you have any thoughts on the motor performance, maintenance, or whatever?


I'm looking at used 2023 vs the newer model with variable timing motor

There is a small difference.  Not nearly enough to make me upgrade.

I'm a 2025 V85TT owner.
Motor has all the power I would ever need and more.
I don't believe there is any add complexity in setting valves.
The bike is very tractable and handling is excellent, IMHO.
As I have noted before, the only complaint I have after 7200 miles is just the bright/dim/momentary switch is easily-pushed-forward inadverntantly when using cruise control with gloves.
This is likely my last bike before the end of my life.
I'm perfectly satisfied with that.

I have a 2025 also, never had the previous version. Setting valves is like all the older Guzzis I have had other than the fact there are no timing marks on the flywheel, rather you have put some sort of indicator in the spark plug hole.
Low end torque is impressive to me. Just the opposite on my 850 LeMans which does very little below 4K RPMs.

Interesting. With the VVT, I would’ve thought there would be no adjustment necessary. Guessing they didn’t go to hydraulic lifters?

Those features are not mutually inclusive.
Still screw and lock nut adjustment.

It likely has a normal camshaft and normal valve train. No drama when adjusting the valves. All they often do is add a device to the front of the camshaft to twist it a bit forward or back relative to the cam chain sprocket.

I rode a '25 v85tt at Barber Vintage Festival last October.  IMO, the '25 has noticeably more low end torque than my '23.  However, l bought my '23 with around 1500 miles on it & balance of the warrantty for about half the price of a new one.  I can't justify buying a newer version for a substantial difference in price for a little more low end grunt when all I have to do is pull a lower gear.

If I was looking to buy a '25 or newer, I'd be more interested in knowing if wind protection, noise & buffeting issues still exist.  I really couldn't tell on during the demo ride last Fall because of the route & speed.

Gotcha, thanks for the clarification. So, is cam-phasing harder on tappets, be they flat, roller, hydraulic, et al?
