Thanks to the Desmodromic Variable Timing (DVT), the engine delivers a very linear and sizeable torque at low rpm, with very sporty performance at higher rpm.

The Testastretta DVT 1262 features characteristic bore and stroke measures at 106 x 71.5 mm, and a compression ratio of 13.0 : 1, delivering a maximum power of 159 hp at 9,500 rpm * and maximum torque of 129 Nm at 7,500 rpm. Fuel is delivered by a Bosch electronic injection system on elliptical throttle bodies having diameter equivalent to 56 mm, managed by a full Ride-by-Wire system.

Moreover, the Diavel 1260 engine stands out for an extremely accurate design; thanks to the water pump being located in the cylinder V, the cooling system pipes are no longer positioned on the left side.

Testastretta DVT 1262 is fitted with a Dual Spark (DS) system, i.e. two spark plugs for each cylinder head, which exploits a secondary air system that supplies cool air into the exhaust duct in order to complete the oxidisation of unburned hydrocarbons and reduce the level of polluting gasses (e.g. HC and CO) without affecting the performance levels.

Maintenance intervals are expected to be every 15,000 km (or 12 months), while valve play must be checked every 30,000 km.
