While the V7III is not expensive in the context of today's $20,000 bikes, I don't consider $10,000 an inexpensive machine.
My Racer came with the excellent Öhlins rear suspension units albeit with springing more suited to a rider who weighs about 150 lbs. The OEM fork felt crude and unresponsive by comparison. So I installed an uprated set of springs on the rear and a Matris cartridge fork kit on the front, with matched springing. Now I have proper springing at both end as well as both adjustable compression and rebound damping to set the bike up with ... Both have needed a couple of fine adjustments over time so having both has been a major plus. Not inexpensive but well worth it, to me.
I also upgraded the wheels so that I could use tubeless radial tires. That was far less necessary than the suspension upgrade as well as far more expensive, but it also improved the bike by a significant and noticeable increment. Happily, I could afford it too. The V7III frame and engine are definitely worth these improvements. It makes me think that the only reason Guzzi didn't include this grade of equipment as stock was to keep the selling price down in the acceptable range; I'd rather have the frame and engine be supported by suspension and wheels/tires that allow them to be used fully.
Both of these sets of upgrades are practically invisible to the eye to the uninformed viewer, so I guess I'm not going to make much of an impression with the custom crowd.
