Overview
The Triumph Daytona 660 is a sportbike produced for the 2025–2026 model years. In 2026, its naturally aspirated 660 cm³ in-line three-cylinder engine makes 94 hp (70 kW) at 11,250 rpm and 69 Nm of torque at 8,250 rpm; wet weight is 201 kg.
Peak power arrives at high rpm, while peak torque comes at 8,250 rpm, so the engine’s strongest output builds as it revs. The 810 mm seat height and 201 kg wet weight matter when stopping and maneuvering at low speed. A 14 L tank gives a calculated full-tank range of about 251 km. The slip-and-assist clutch helps calm the rear wheel on hard downshifts, and the Showa front forks adjust for compression and rebound while the rear shock has preload adjustment.

Pros and cons
Advantages
Adjustable suspension
Compression and rebound damping adjustments at the front, plus rear preload adjustment, let riders tune the suspension to suit their setup.
Slip-and-assist clutch
The assist function reduces clutch effort, while the slipper function helps calm the rear wheel during hard downshifts.
ABS braking
ABS operates at both ends, with twin front discs and radial four-piston calipers providing the front braking setup.
Things to consider
810 mm seat height
The seat height can make it harder for shorter riders to get both feet firmly on the ground at a stop.
201 kg wet weight
That weight has to be managed when pushing the bike around or maneuvering it slowly.
Chain final drive
The chain needs periodic cleaning, lubrication, and adjustment.

How to measure
Stand barefoot with your back to a wall. Hold a book firmly between your legs, then measure from the floor to the top edge of the book.
Estimated ground reach
Both feet likely flat
You should have a stable stance at a stop, although seat width and suspension setup still matter.
