Lengths derived from that of NAMI Logan 4-Piston (Burn-e) which is the most generous of all common 11" wheel scooters.
Hose terminates on the inside of calliper, on a slightly more favourable angle than that of Logan 4-piston to help clear tyre sidewall (see notes). The inside termination reduces exposure of hose to damage and the factory crimped connectors form a robust connection on both ends. As the termination is crimped, clearance to route needs be accommodated as mentioned below in notes (alternatively use existing hose).
