The ST1300 keeps the configuration of the ST1100 engine, but virtually nothing else. Still a 90-degree V-4 situated longitudinally, the new engine is 16% larger in displacement (1261 cc compared to 1084 cc) with the "big bore/short stroke" design popular in current sport bikes and racing machines.
Producing 125bhp @ 8,000 rpm, with 85 pound feet of torque at 6,000 rpm. The bigger displacement and the sportier bore/stroke ratio are just part of the performance boost received by the ST1300. Significantly higher compression (10.8 to 1 versus 10.0 to 1), as well as much larger valves, also play a role. The result is engine performance that significantly exceeds the ST1100.
The ST1300 is now fuel injected, Incorporating a throttle sensor, and 3-D injection and ignition mapping, Honda was able to achieve much higher performance levels while meeting the most stringent Euro 3 emissions.
The new engine runs even smoother than the ST1100 with to dual engine counter balance shafts that virtually eliminate primary and secondary vibration. This was as much to improve handling as to improve rider comfort . The smoother engine is solidly mounted to the chassis as a stressed member for improved rigidity and reduced weight.
The engine contributes to performance by being significantly more compact. A full 50mm shorter than the ST1100 engine, the new engine benefits from a relocated crank shaft, lighter and narrower cam chain, and more closely integrated five-speed gear box.
The best touring machine in the World? Unequivocally!
