The new engine, whilst still 675cc, has a wider bore and shorter stroke, allowing for a 14,400rpm limit. This gives more power, 126bhp, and a broader spread of useable revs. Peak torque is 55.3lb/ft at 12,600 rpm.
The engine has a new block, separate from the upper crankcase, with ceramic coated aluminium bores and titanium valves. There's also a new slipper clutch and improved engine management which opens throttle butterflies to reduce engine braking.
The new, lighter frame uses fewer sections (four rather than six) for a stronger, stiffer design with sharper geometry and shorter wheelbase. The suspension on the standard version is fixed cartridge forks by KYB (Kayaba) and a revised rear shock. The 675R comes with an Öhlins TTX rear shock and NIX30 inverted forks.
The exhaust has been moved from under the seat to tucked in behind the engine, as with the new Street Triple, to move weight forwards and downwards in order to increase stability at high speed and agility at low speed.
ABS is an option on the standard 675 and standard on the R and comes with a switchable track setting. Prices are £8,899 for the Dayton 675, £9,249 for the Daytona 675 ABS and £10,599 for the Daytona 675R ABS.
