Aprilia_RSV4_0008
This is the next generation of large Aprilia superbikes and, according to the factory itself, it’s the closest motorcycle they’ve ever made to what you see racing in World Superbikes every other Sunday of summer.
And right from the off during the world launch at the Misano circuit in Italy, the quality and ‘things-borrowed-from-race-teams’ is clear. The throttle pick-up, from 2000 to 14,000rpm, is instantly amazing. There’s not an engine underneath you but a supersmooth turbine of pure power. Flicking the bike through a few corners it’s clear that you’re riding something crafted by those who know about suspension.
Pick a line and the RSV barks obligingly and hurries along it. The brakes are WSB stoppers on the new front end and hit them hard enough to get the bike just lifting the back wheel and the new chassis (longer, lower centre of gravity, much more stable) isn’t phased.
In short, the first two laps of a circuit tell you everything you needed to know about this bike – the three elements of the modern superbike – are sorted and better than you could have hoped for.
The engine, all-new with a host of race-bits as standard is in the 200bhp club, 16bhp up on the old engine and is an absolute gem to use.
The chassis is all-new with a lower centre of gravity, a longer feel and pulled-in steering angle. It’s super clam and wonderfully easy to flick about.
The riding position is roomy, involved and whilst you’re not slotted ‘into’ the bike, you’re not perched on top of it. It’s almost the perfect compromise no matter who you are. Looks small but feels much bigger.

Tell me about the engine
That motor is luscious to use and has been vastly improved with more efficient machining and more clever electronics. Deliberately going into slow corners a gear too high doesn’t worry it, the electronics save your momentum and the engine note drops but it can stand hamfisted abuse. The power builds rapidly as you stir the pot and it’s so responsive (and gives a great ‘boost’ from about 8000rpm onward) that there’s a real delight in letting the bike rev and holding a gear between corners.

What’s the chassis like?
That chassis with the Sachs rear shock is predictable and tiny in feel. Where a month ago I was dragging the whole of the side of my boot on the floor on the Yamaha R1, on the RSV my toes never touched the track. That gives you some idea of just how narrow this bike feels. It never dominates the rider, mostly because it’s physically as intimidating as a nice pair of slippers.
The riding position puts you at less of a radical pitch to the bars than on the Tuono sibling. The bars feel wide at first but make sense on the move and that fairing is both easy to get under and absolutely brilliant at keeping the wind off.

How are the electronics?
Playing around with sub-routines in the digital brain isn’t straightforward however. It’s definitely worth investing time with the RSV4 and learning how to set up the myriad of options that you can dial in for traction control, throttle and anti-wheelie settings. I dropped the traction control over the course of a 20 minute session and from 7 to 4 there wasn’t too much difference in terms of feel, but 3 found the bike sliding just on the edge of my skillset. It’s a very sophisticated system in truth and knows your lean angle, throttle aggression and acceleration rates as you ride. You never feel the system butting in to the ride though, it’s seamless in its interaction and never detracts from sheer and repeated joy of cracking the throttle and listening to that V4 howl.
Turn eight at Misano is crucial because, like many turns at the track, of the straight that follows it. You jet along the track, lean into turn nine – but use it as part of the straight – and then fixate on braking for turn ten. I found that going into turn eight in second was fine but eventually I opted to hit turn eight in first, just so I could keep the revs high and enjoy a small slide on the exit. This happened after one session on the RSV and tells you just how at home with the RSV a new rider feels almost straight away.
Aprilia was at pains to ram home the message during the launch that this bike was built to echo the first RSV4 in 2009: the best, uncompromising superbike and one that comes closest to the real racing bike.
Without riding Haslam’s factory RSV4 it’s hard to say how close to that goal they’ve come with this bike, but what is immediately obvious is that here is a massive step forward for superbikes once again.
The RSV4 is an immense motorcycle. But at £3,000+ more than the Yamaha R1 it might find that it’s roundly beaten in the sales stakes. The track however, is a wildly different matter.
