Triumph aims to keep both iterations of the Daytona fresh, so for 2013 the company has given the bikes the most intense overhaul to date. “A few tweaks would have kept the 675 on the pace, but the 2013 Daytona is set to raise the bar once again,” says Triumph. To that end, Triumph re-engineered the Daytona's 675cc triple with a larger bore and shorter stroke, new titanium valves, twin injectors per cylinder, and reshaped intake and exhaust ports. Redline has been raised to 14,400 rpm, and Triumph says that both horsepower and torque numbers are are up, with a broader midrange spread to boot. Owners asked for a slipper clutch, and Triumph delivers: the 2013 bike has a slip-assist clutch like the one in the new Kawasaki ZX-6R, which offers a lighter lever pull and smoother downshifts.
