Description
LTH racing exhaust "Midrange" for Vespa PV, V50, PK
The middle between LTH Road and Race exhausts. The midrange delivers nearly as much horsepower as the Race without the disadvantage of the big weakness at low revs. This makes it perfect for kart track racing and using a powerful smallframe on the road.
optimal exhaust port timings:
Road: <180°
Midrange: 180-190°
Race: >190°
incl. fitting material
The exhaust is also know as the RX-1
The toolbox can still be used.
The diragram is from a Parmakit Test
The midrange is the purple one, the data is on the second page
With 26.3hp at 9000 rpm and 21.6 nm at 8000 rpm the Midrange is a fine option for the Parmakit. The power kicks in relatively soft at low but still produces a lot of power, this makes it a perfect exhaust for ESC racing or road driving.
