Moto Guzzi V9 Bobber debut

Having said all of that, hard to beat the 'valve adjustment requirements' for a Harley.

Of course it's fair to take related maintenance into account, and HD tappets are basically a periodic replacement item. Tappet rollers frag, pins back out gouging tappet bores, hydraulics wear and bleed down, and being heavily loaded cam lobe wear is high on HDs.

OTOH shim and bucket systems on street bikes rarely need adjustment and their engines turn far higher RPM and often make more HP than even heavily modified Harleys without a single MoCo part in the engine.

---------------------

Guzzis are neat bikes. Contact Guzzi owners clubs and be prepared to do your own wrenching if you don't live near a dealer. The engine design is easy to work on though. They are Harley-tier simple.

This is a huge misrepresentation.

Anything CAN break. That requires a repair.

Maintenance is the planned service which is suggested to prevent the need for repair.

Hydraulic lifters are generally lifetime components.

Shim and bucket valves generally require periodic checks to make sure they are in spec.

And Guzzis don't use shim and bucket valves but that's another story.
