Doppler WR7 exhaust system for early Aprilia RS 50 models

The Doppler WR7 exhaust has slowly been replacing the earlier ER1 systems although the WR7 expansion still keeps with a very similar design. Boasting the latest WR7 silencer design and impeccable performance through a very broad RPM range, the WR7 is a serious contender to many other systems on the market whether you’re using it on a 50cc or tuned 80cc machine. Suitable for all Aprilia RS 50 models up to 1999.

NEW! Doppler WR7 Exhaust Systems

The latest shipment of moped parts to land at Pedstop HQ include the new Doppler WR7 exhaust systems. Aimed at people serious about moped tuning these are the highest spec Doppler exhausts available for geared mopeds. The WR7 features a newly designed expansion giving more power low down whilst keeping that power band up at high RPMs like the ER1 systems do, and they carry on to rev out a little bit further. The new silencer is completely re-designed in a titanium colour with anodised black end cap (which we think looks far better), it’s also 300mm longer than ER1 systems which also reduces the noise.
