It’s a fantasy that every road bike owner must have had at some time in their lives. ‘What if I could build a bike that was invisible to radar?’ The thought of those charming boys in ‘law enforcement’ totally unable to get a reading on you as you glide through your favourite set of corners. And not at a speed calculated to be ‘safe’ for everyone from the tanker truck full of petrol to the little old lady with failing eyesight, but instead at speed that perfectly suits your skills, the bike’s performance and the conditions of the day. It’s what the afterlife must be like. The afterlife and whatever inspired the owner of this beautiful Yamaha to brief her builders, Portugal’s It roCkS!bikes, to turn his stock XJR into the two-wheeled equivalent of a Stealth Fighter you see here.
