Here is the DOPPLER exhaust model ER1 carbon edition for MBK 51. This good quality exhaust has a nice look, high performance and a fair price. The body is a real rolled welded in 1.2mm sheet metal with a varnish finish.
The sheet metal is of good quality, the volumes, shapes, counter cones… Are well studied! This pot works very well on an original cylinder and on small 50cc kits (DOPPLER ER1, BIDALOT G1 Replica, AIRSAL T6, fox engine ...), it will not offer good performance on very sharp engines (from a its sheet too thick) nor on large displacement engines (due to its architecture and volume).
We would say that the diagrams adapted to this exhaust go from 178 to 185 ° maximum, with a power regime of 9000rpm maximum. This exhaust is really solid and very quiet with its absorption cartridge filled with ceramic wool. This version has a real carbon silencer in order to lower the weight as much as possible and to give a beautiful aesthetic side! It comes with fixings and all accessories. Look level, it is really nice and racing, it is obviously delivered with an approval certificate, it is clamped at the entry of the ball joint, be careful, if you remove the entry washer it is no longer road approved.
To close, this exhaust has a very racing look like the GIANNELLI SPORT and NINJA G2 Replica for example, it is really not noisy and very solid, it will adapt with a small configuration type 50cc kit, carburation 15 to 17 , 5mm, variator… However it will not follow on 70cc and large 50cc kits with large diagrams. Really a great pot to roll every day.
