friend and a flat stiff chassis is .
WHAT ’ S DIFFERENT ... AND THE SAME The S model has a slightly different power delivery to the Pro XP . The Pro XP punches hard from the get go and is then linear and strong right through the rev range while remaining very drivable in slow tricky conditions . The S has a little less from low revs and through the midrange , but is very strong up top – it feels every bit as quick as the Pro XP when going hard . Just above idle the S has a tiny surge that makes it a little tricky when wanting to go forward 100mm and not 200mm ... I really only noticed this when loading it on the trailer , so it ’ s not a huge deal . The braking performance is excellent on both machines , with four-wheel hydraulic discs at each corner . The calipers are three piston units up front and two at the rear . Stopping power is strong with great feel and no sign of fade at any time , although speeds were not fast that often . The electronic power steering is well weighted on the 64-inch Pro XP with excellent feel through the wheel and accuracy . On the 74- inch Turbo S there was noticeably greater torque steer and bump-pull through the steering wheel , mainly when hard on the gas . Under full power if you hit a bump with the right front wheel you needed to hold firmly , or even steer to the left upon impact to stop being pulled off-course to the right . While this was entirely manageable , it was quite hard work and would be tiring over a few hours at race pace . Also , the extra 10 inches of width meant it was definitely a bigger machine to manage on tracks and in the tighter going , but it was more stable too on rough ground and in turns . A catch 22 thing I guess , or horses for courses . Both machines had a great steering rack ratio that meant catching slides and general use never required multiple turns of the wheel . Also , both have 2WD / 4WD selection on the
