Aprilia Tuono (2003)
I love this bike. It had been almost a decade since my last new bike (a 1994 Ducati M900 Monster). Things advanced a lot since then. I loved my old Monster, but every single aspect of the Tuono was better: the chassis, the handling, the power, everything. OK, except 1 thing: the Monster sounded better. A 90 degree V-twin is one of the best sounding engines ever made. The Aprilia is a 60 degree twin which allows the engine to get packed closer to the front wheel, but it sounds "raspier' than the Monster.
I used to think that if I had to sell all the bikes except one, I would keep the Yamaha SRX-6. Now, I figure it would be this one.
Update in 2021: I still own the Tuono, it is still great. Nowadays, I am sure that if I ever go back to one bike, it would be the SRX-6. The reason? The older I get, the less I need the completely bonkers riding experience of the Tuono.
As everyone who owns a bike knows, they don't stay stock for very long. This one is pretty close though, especially if you compare it to what other people do theirs. The short list of modifications so far would be, well, short:
Ohlins rear shock
Ohlins front fork internals kit
And that's it.
The one thing that bugs me is that it only gets about 32 MPG, which means that its range is only about 130 miles. According to the Aprilia Forum discussion groups, I should check the fuel pressure. The members there claim that low gas mileage usually means high fuel pressure. ...Or maybe just a heavy throttle hand.
So for now, the bike is great. I will mess with it though. It's just the nature of bike ownership.
Problems so far:
The stock rear shock leaked oil since day 1, hence the replacement with the Ohlins unit.
When the bike was uncrated at the dealer, the rear tire was flat. Seems that the factory-worker who crated it up had inadvertently secured the rear tire to the bottom of the crate with their nail gun.
The alternator connector cooked itself. Replacing the connector is an expensive, time-consuming option, so I just cut the old connector off and jumpered a new set of wires across it. This seems to be a common Aprilia problem.
2021 update: The clutch slave cylinder seal failed. This is another common issue with the Brembo clutch slave cylinder used on the bike. The repair was $8 for a new seal, followed by a really easy replacement job. The original seal lasted over 18 years, so I'm not complaining.
The biggest problem with the Tuono is that the bike eats tires. Here is what remains of a Metzler M1 Sportec after about 2000 miles of commuting to work up and down Black Road in the mountains of Los Gatos, CA:
It would seem that I spent more time turning left than turning right or going straight. It sure was a fun commute though!
