Ducati 748r
Ducati 748R
Title chaser
DUCATI DOMINATED WORLD Superbike (again) last season but played a comparatively minor role in World Supersport. With the latter series gaining in popularity, both among fans and manufacturers, the Bologna-based bike-maker felt it important to try harder.
Witness the new 748R.
While the original 748 was designed to broaden the 916’s appeal, this latest model has an even greater global mission. As such, there are three build levels: 748 “Entry,” 748S and the aforementioned 748R.
The R is a racebike with tumsignals. Drawing from Carl Fogarty’s title-winning 996, the 90-degree V-Twin was completely re-engineered. It now produces 106 horsepower at 11,000 rpm, with 57 foot-pounds of torque at 9000 rpm. Compared to the previous 748 SPS, that’s 4 more horsepower at 500 fewer rpm. For even greater gains, Ducati will produce two engine kits. The “A” kit is good for 6 more bhp, and the race-only “B” kit adds 16 bhp. Prototypes have produced 126 bhp, well above last year’s factory race entry.
With the goals being a broader and flatter torque curve, plus additional peak power, the airbox was enlarged and the intake runners incorporated into it. The runners themselves are shorter than before, which created a supercharging effect and produced dramatic gains in volumetric efficiency. Bigger valves, 54mm throttle bodies and new cam profiles complement Formula One “shower-type” fuel injectors, one per cylinder. Combustion chambers are machined via computer, ensuring a clean, consistent profile.
Chassis changes mirror those made to the current 996 Fogarty Replica. All components are of the highest quality: fully adjustable Showa suspension, Brembo four-piston calipers with 320mm discs, five-spoke Marchesini wheels and Pirelli Dragon Sport Evo Radiais.
At the Misano press introduction, the 748R rewarded testers with remarkable steering and superb balance. Power was progressive and smooth, and never overwhelmed the chassis. Gearing was a bit tall, but because the engine pulled vigorously from as low as 4000 rpm, sixth gear could still be used to reach an indicated 137 mph down the main straight. Actual top speed is reputed to be 162 mph.
Put simply, Ducati has done it again.
