Exhaust Doppler Doppler ER1 MBK 51

Doppler Exhaust ER1 MBK 51 by famous French manufacturer Doppler.

The expansion chamber is made of sheet metal (rolled and welded) and coated, the silencer is made of chrome-plated aluminium (absorption-type). This well-designed exhaust will yield a considerable increase in power, especially at mid and high rpm range.

Though street-legal, this exhaust is very powerful and can easily be combined with original or 50cc/70cc sports and racing kits.

Please note: TPSI approval only valid in France but not in the rest of Europe.
