The 2013 Daytona 675Rs engine is now even more focussed. We’ve built it with a new shorter stroke and wider bore dimensions for even more useable power and acceleration. The cylinder block is now cast separately from the upper crankcase to cope with higher pressures, more torque and more power.
In addition to the 675, the R now comes with a quickshift gearchange, reprogrammed for 2013 to give you even faster, smoother shifting.
With twin injectors per cylinder the new Daytona can draw more fuel quicker when you open the throttle fully and demand more from the engine.
A first for a production Triumph, we have now fitted substantially lighter titanium valves to cope better with the higher revs. This also means lighter valve springs can be used, reducing valve train wear and friction.
We also knew that the weight reduction was enough to give us the space to add some metal to the valves without compromising the valve train, so the top of the valve ‘mushroom’ heads were reshaped to improve gas flow around the valve and into the combustion chamber. This means better efficiency and a boost in torque at low and medium revs.
We enlarged the throughairflow headstock so that the intake mouth is positioned in the highest pressure zone centrally at the front of the bike. Improving flow efficiency, so that air passes in a straight line through the centre of the headstock to the airbox.
And when the air passes through the centre of the cockpit zone, it gives you even more of that distinctive three cylinder intake snarl. And it’s not just the volume of the sound that’s better, it’s now there over a much wider range of revs for an even more focussed, involving ride than ever before.
The overall theme for this bike is more torque, better acceleration and more useable power.
One of the main contributors to this is the improved bore and stroke. We built the latest Daytona 675R with a shorter stroke allowing us to set a 500rpm higher rev ceiling at 14,500 and we increased power to 128PS and maximum torque to 75Nm. So the new engine now gives you higher power for longer. Wringing even more performance out of the bike as well bringing more of the rider out of you.
