An elaborately constructed expansion chamber exhaust system for the BFA cylinders designed for the Vespa largeframe models.
This racing exhaust for the BFA 306 motor belongs to a group of components designed for exclusive use with the BFA engine casings.
This is not restricted to the flange fitting the exhaust outlet on their cylinder，but extends to being specifically conceived to complement their capacity，port timings/cross sectional areas to produce a strong and harmonic power curve.
very wide performance band
Optimum function on BFA 306 or 225 engine
very elaborate and nice fit
As with all BFA products，these exhaust pipes are manufactured using the most modern and elaborate production techniques.
To smooth their radii and create more harmonic curves，these exhausts are welded together from 32 single segments.
This makes their construction especially complicated and time intensive but guarantees maximum exploitation of the potential power provided by the cylinder.
The BFA exhaust is available in two versions for the Vespa largeframe models：
for the 306cc cylinder (50mm flange diameter)
for the 200cc cylinder (44mm flange diameter)
As the BFA cylinders have outlet port cross sectional areas correlating specifically to their transfer port system，the exhaust flange diameter is not compatible with original Vespa motors.
The BFA exhausts cannot be fitted to a cylinder compatible with an original PX motor type and aftermarket Vespa exhausts are not compatible with the BFA motor.
Technical features：
- 32 steel segments
- O-ring flange
- Aluminum muffler
- Mount with 2 rubber buffers
- Lefthand
Its flange is attached to the cylinder with four bolts，at a distance of 60x35mm to each other.
The BFA race exhausts possess an extraordinarily voluminous diameter，but thanks to careful routing，good cornering clearance remains available.
The BFA exhaust is delivered unpainted and also has an aluminium silencer unit.
When combined with the BFA motor over 50PS are easily available，plug and play！
Conclusion：An exhaust，with a specification and production quality to match the race technology of the BFA Vespa largeframe motor perfectly！
Racing Exhaust/ normal steel/ aluminium silencer/ lefthand exit
steel clear powdercoated，32 segmented and hand-made，bolt-on silencer aluminium，lefthand，rubber sheathed fixing springs.
Difficult to combine with wider-section tyres，main stand use also still possible.
Jetting and ignition timing should be checked and adjusted.
SIP - TIP：Do not forget to order an exhaust paint (e.g.
black：＃14070000 or clear：＃14072000) to enhance the overall appearance of the motor.
