You don't have to read

We don’t force you to read like those other print-only publications. Here at MO, we let you choose. We offer up our opinions both here and on the Youtubes. In the case of the 2021 Aprilia Tuono V4, I was able to score the Factory model for some extra testing which allowed more time to use the bike around town and the opportunity to weigh and dyno the machine before shooting the video below.

2021 Aprilia Tuono V4 Review – First Ride

I’ve owned a Tuono since 2016, and it was a purchase that I’ve never regretted, even now as it sits with electrical issues that I’ve neglected to take care of (it may have been my doing, we’ll know when I finally get someone more competent than I to check it out). The 2021 model is better in nearly every way, although mine has more of a raw bark to its exhaust note. That is likely due to the ever tightening squeeze that Euro 5 demands of new machines – which the Tuono has succumbed to. None of the thrill is lost though. The 1077cc 65-degree V-Four still packs a punch.

Judging by that flat spot after 9000 rpm (and things we’ve read on the internet) we’d surmise an ECU flash could pump some more power to the rear wheel.

Aprilia says it hasn’t sacrificed any power to the new emissions standards. The dyno has it making 0.7 hp less and 2 lb-ft more than the last time we dyno’d the big V4 (they were run on different dynos though). The chassis remains one of the best, and its stability and ease of placing the machine exactly where you want it hasn’t waned.

What Aprilia has managed to do with the electronics package and other subtle refinements over the past decade has brought to the market an improved version of the hypernaked bike we have come to love here at MO. I’ll stop gushing though since you’re probably not here to read what I have to say anyway.

    The fully-faired "naked" bike. I really want to test ride one, but the seat is sky high for me.

    White one doesn't look too bad. They need to ditch the stupid "a" on the fairing and drop the pegs a couple of inches. Aside from that, it ought to be a darn nice standard bike. Overkill for sure, but V4s are nice mills.
