Enfield brake upgrade complete:
I have now fitted a 4 piston Brembo calliper, and larger 330mm diameter floating rotor to my Royal Enfield 650.
A 6.9% increase in piston area plus a 3.125% increase in brake torque from the bigger rotor.
I had to design and make some custom parts to make this work, and I made a few extra sets if anyone wants to do the same upgrade:
Calliper bracket
Rotor spacer
ABS pickup ring
ABS sensor mount
The Brembo P4-30/34 is shown, however a larger piston, 4 pad, P4-34 calliper has just arrived and will fit it next
20.2% greater piston area than stock plus the same 3.125% torque gain from the 330mm rotor
