Complete Doppler ER1 MBK 51 liquid cylinder kit

The ER1 cylinder features a 5-port scavenging system with booster exhaust ports, made of aluminum. Being aluminum for better heat dispersion, it has a Nikasil coating. This provides a low-friction and highly durable surface. The elliptically shaped piston has a single segment (thin 1 mm) made of hard chrome-plated steel. DOPPLER recommends pairing its cylinder with the DOPPLER cylinder head.

The KIT includes:
CNC black anodized aluminum cylinder head with a bi-hemispherical chamber, and without a decompressor.
