Wat kopers moeten weten
MV Agusta Engine Heritage
The 921cc inline-four was created in collaboration with MV Agusta and is essentially the sleeved-down F4 1000 engine that powered the 2011 Brutale 920. It retains Magneti Marelli fuel injection but has been modernised with ride-by-wire throttle and Euro 5+ exhaust.
Competitive Price Point
The SRK 921 RR is priced at just £8,999 plus £300 on-the-road charges, making it cheaper than rivals like the Ducati Panigale V2, KTM 990 RC R, Yamaha R9, and even the less powerful Yamaha R7 and Aprilia RS660.
Engine Fault During Testing
During performance testing, the RR developed an engine fault that prevented MCN from completing their test. QJMotor's UK importer stated the bike had entered a protective limp mode and was investigating whether any engine damage had occurred.
