Dzinēja atspere Doppler Soft balta Peugeot 103 / MBK 51

Engine Tension Spring Doppler Soft white Peugeot 103 / MBK 51, spare part for the Doppler ER1 engine springs that are used to stabilize the engine at high rpms. The spring is placed between frame and engine; it stabilizes the movement of the engine and adds resistance to the variator opening.

The spare springs are available in different strengths; a harder spring means more resistance to the variator opening which can lead to better acceleration. The original (hard) spring may be a little too strong for less powerful engines, so Doppler decided to offer additional softer versions as well.

White = soft (softest version).
