The V4 engine, taken directly from the RSV4 R superbike, suits the Tuono perfect with an absolute abundance of power. Aprilia has only de-tuned it slightly, down only 13 horsepower short of the RSV4 R. The Tuono is hard physical work when it hits the higher revs as I really have to push myself forward to avoid hanging after the bike by the handlebar. The Tuono munches up all the short straights at the Ricardo Tormo circuit like nothing else, and quickly it seems the whole circuit is a succession of corners with one long start/finish straight.
With the APRC traction control I can accelerate early from great lean in safety, and even on level one it feels safe despite some nice sliding action out of most corners. The only place on the Valencia circuit where there’s some room for relaxation is down the straight, but even here the enormous power and the wind pushes you back until it’s time for hard braking whilst shifting down the box.
Later in the day I preferred to short-shift up the quick shifter more to save my arms from the strain, and it hardly felt like I was going any slower. The three lower gears on the Tuono are lower than on the RSV4 R and it can be felt! Due to that great quick shifter I also made my way all the way up to sixth several times down the straight. The slipper clutch is equally good when shifting hard down to second ahead of the fast left-hander at the end of the straight. Then it’s all full throttle and sliding and a little wheelie all over again.
