Well, after ummming and ahhing over upgrading to the latest version speed triple , I went on a test riding weekend, and rode the Street fighter S, 2011 speed triple and the New Aprilia Tuono V4R APRC. As the title suggests, the Tuono won out . It's an amazing machine, all the things I love about my speed triple with a rocket engine and the latest Tech ! There is no doubt the streetfighter is an amazing bike, but i felt i wasn't a good enough rider for it ... it was hard work ! Even ignoring the $10K + price difference, The Tuono is just amazing, and possibly a better bike. the APRC system is great ! - traction control - 8 levels - wheelie control - 3 levels - Quick shifter - Launch control Wheelie control when set at level three allow NO wheelies - the fun police, lower levels allow for longer higher wheelies up to 30 metres. Traction control - i tested a few settings (all available on the move) and once you start to trust it , and with wheelie control on three, you can use the throttle like a light switch... and HOLD ON !!! you can feel the smarts at work as the front gets light, and once that moment passes the power rolls on. great stuff ! The star of the show is the quick-shifter.... nail the throttle and go , changing up with the throttle locked takes some getting used to but man... its addictive, and AWESOME ! Of course the V4 sound is fantastic , even with the stock pipe, which i will be replacing ASAP. The new tuono is also ride by wire with 3 standard maps, Road - cut down power by 25% for wet and casual riding Sport - full power, smooth delivery Track - BALLS OUT Been on a couple of test rides, and put down my money expect delivery in early Jan... Cant wait !
