A Review of the Aprilia SXV 550: Unleashing Power and Precision

The Aprilia SXV 550 is a true beast on two wheels, combining power, agility, and precision in a single package. Built for off-road enthusiasts, this dual-sport motorcycle offers an exhilarating riding experience like no other. In this comprehensive review, we will delve into the key features, performance capabilities, and overall riding experience of the Aprilia SXV 550.

THE BIKE The first Aprilia RXV 550 to hit the market in 2006 was an animal. It was scary. It had a light switch for a throttle and more ponies than the Ponderosa. On a test day, while doing 140 kph on a flat dirt road, I listened to the rear wheel screaming for traction and wondered how you’d ever get the thing up a hill – and how I was going to pull up at the next corner. I wasn’t keen to get back on it any time soon, and yet here I am, all suited up and ready to roll on the 2007 model of the wicked Italian.

BELLEZZA (Beauty)

What I see before me is still the best-looking dirt bike ever crafted. Italians know style and when the quest for the balance between form and function is seriously chased, they often come through with the goods – they invented the Yo-Yo for heaven’s sake! And of course, Ducati, MV Augusta, and Cagiva, not to mention Aprilia’s own stunning gifts to the road bike world are all ‘messo in modo bello’ (beautifully crafted).

It’s hard to know where to start when describing the RXV. Its predominantly black and red color scheme is striking, as is the lion’s head on the radiator shrouds and the super-aggressive front and rear guards. Then there’s the frame – or lack thereof.

The forward part of the frame is non-existent and the job is instead done by making the engine a structural part of the bike. It looks great, but there’s nothing to stop the engine from taking a direct hit from a log or ledge, so a bash plate is a necessity. It’s packing a fairly healthy 396 mm of ground clearance, however, which compares well to the current king of the big-bores, the KTM 530 EXC-R, which has 380 mm.

The twin pipes slink their way up under the seat and peer out from under the rear guard. Heat can be felt as it builds up under the seat but it’s not unbearable, and anyway, we reckon those pipes look so sweet you can take some heat for the pleasure.

The speedo is a very compact and sturdy-looking LCD unit that tells you everything you’ll need to know, with a scroll button cleverly mounted on the left-hand switch block. The keyed ignition means you can stop for a pie and not be so worried that a scumbag will pinch your bike.

To access the paper air filter you have to get under the tank and it’s a fiddly job that doesn’t suit a dirt bike all too well. Overall, access to the engine isn’t easy given that the twin-cylinder donk takes up every available millimeter of space. It looks like something you’d see on a road bike but doesn’t lend well to on-the-trail, middle-of-nowhere maintenance.

The seat comes off easily enough through a single Dzus fastener, while undoing a hex bolt near the steering head allows the fuel tank to hinge upwards to reveal the airbox – underneath which is the engine – but not much room to do anything with it.

None of the RXV’s beauty is diminished – and even a few of its shortcomings are forgotten, however – when the engine fires to life. It revs in short, sharp explosions of power, testosterone, and deep guttural joy. If Harley owners are still under the impression that their bikes sound fantastic, they best not saddle up next to the RXV at a set of lights because it’ll destroy all their dreams and rattle their tassels to the core. Stop me if I’m gushing, but I went through half a tank of fuel just revving the bike in between gear changes.

So, after a look at some construction details, you’d have to say the RXV is a little more form than function at this stage. Let’s get it on the dirty gear and let the ponies run.

FLAT AND KNACKERED Of Aprilia SXV 550

Starting the RXV was a problem. The battery was dead and didn’t build any charge even after several hours of riding. It was a push start for the whole day, and I don’t need to tell you how much that sucks in 34-degree heat and on flat ground with a 119-kilogram-plus (claimed dry weight) machine. Neither the 450 nor 550 have a kickstarter, and fuel-injected V-Twins take some voltage to get fired up. Function was losing to form again.

RAZZO ITALIANO (Italian Rocket)

Powering your way through gears for the first time, and you very quickly find that this bike is like nothing else on the market. If the RXV’s problems are sorted, Aprilia has something very special on their hands with this engine. The power is still monstrous but the delivery has been cooled. It’s much more controllable over the ‘06 model, thanks to a new oval design in place of the original round kit, and the way it feels when you open the throttle is near a religious experience.

The engine is smooth and the bike shows no vibration as you wind your way up the track, where the cue to change up a gear is given when the rear wheel is spinning faster than the earth’s rotation can match. With all that power to play with, it’s surprising how easy it is to keep it in check and pick your way through tight stuff.

And believe us, it’s obscenely fun. Sure, it’ll catch you out every now and again, and it’s not unusual to find yourself completely sideways with no notice, but it never seemed difficult to bring back in line, even when seemingly we were past the point of no return.

Up front, the fork does a great job over most everything, but the very quick steering can have the RXV pushing through turns, deflecting off sharp ledges, and off-camber corners are a bit nerve-racking. A bike this strong can afford to have slower steering because you can steer with the back wheel. The rear end has the dubious job of keeping as much of the bike’s power to the ground as possible and still soak up the hits. It does kick at times under braking, but a little tuning would probably help there. The brakes are, thankfully, excellent. They’re strong, predictable, and well-balanced on any surface.  

Although we had to push start it every time we stopped, the Mad Monkey test crew was still upbeat about the RXV until the unlikeliest problem arose. After 47 kilometers, the fuel light came on, and since the bike is fuel-injected, there is no reserve.

This is no good. A big bike should take you a long way. Hell, even a little bike should take you more than 50 kilometers. So, after pushing it all day in the heat and then – halfway through our usual ride distance – the bike starts running out of fuel! We got pissed off and called it a day. We were out of fuel at 50 kilometers and wow, what an amazing 50 kilometers – but a twin-cylinder enduro bike of this size needs more than a 7.8-liter tank.

ALMOST THERE

All that power produces wheel spin that robs the bike of juice and destroys rear tires in a flash. Is it worth it? Kinda.

The bike is in its second year of production. If Aprilia engineers are on the ball and the fuel, battery, and front-end issues can be sorted, I’ll put my hand up for one in my garage. It’s simply the most exciting bike we’ve ever ridden – the most amazing big-bore engine on the planet – and there are some other clever ideas at work here. Give it some time and hopefully, it will come of age, but right now the ledger is more on the form than function side, and although the RXV is a blast to ride, I don’t think I’d want to live with it…yet.

WHAT THE BOYS SAID:

EVAN ROSE – Expert

Hits:

Responsive engine with plenty of usable power throughout the rev range Overall, the bike feels a lot smaller and lighter than expected You’ll ride with a smile on your face!

Misses:

The upper part of the seat is uncomfortable and makes it difficult to lean forward on the bike in tight conditions The front suspension is aggressive and often deflects in rocky conditions On a hot day and after a few hours of riding, the seat becomes uncomfortably hot Fuel consumption is too high

Would you have one in your garage? With 550cc of V-twin power, it’s awesome. The bike has so much power that many of its negative aspects are forgotten after the first twist of the throttle. It’s great!

MARK HARGRAVE – Expert

Hits:

The engine is an absolute colossus It has more power than any mere mortal could ever ask for The throttle response is razor sharp, and combined with the impressive torque, it allows the engine to be run in a higher gear (or even two gears higher in my case) while still being able to accelerate seamlessly to warp-speed. The rear end easily absorbs most trail debris and has a remarkable ability to return straight after sliding sideways under acceleration – which happens quite often.

Misses:

The front end tends to deflect and tuck under when leaned into corners, making it somewhat unpredictable Due to the unusual shape of the fuel tank, the shrouds initially felt uncomfortable and stuck into my legs as I tried to lean forward in the saddle, but this feeling subsided as I rode the bike for a while.

Would you have one in your garage? Hell yeah! Who wouldn’t want a bike that looks this good and gives you a tingling sensation in the loins every time you twist the throttle? If I were riding in tight, hilly terrain for a day, I’d leave the big girl at home, but as soon as the riding involved open fire trails or grass tracks, it would be the first bike I’d fire up.
