here's what ya get in this PARTYYY!:

good evening passengers, this is your captain speaking. up ahead in the stratosphere is a USA-made, NASA inspired water cooled head specifically made for vespa 43mm polini kits! should also work quite well with malossi 43mm kits, DR 43mm kits and all other vespa 43mm kits as well.

note this will ONLY work on subframe model vespas like grande, bravo, SI, citta, grillo, boss, etc. this will NOT work on ciao because it won't fit in between the frame!! sorry!!

buckle up amigo, time to blastoff to the future!!!


- one piece design, 100% sealed against seam leaks
- bolt on fittings with perfectly matching o-rings on each side
- fittings have 360 free range of motion, ready to be bolted down to your desired angle! comes with 2 bolts.
- uses normal bhs plugs
- this head is NON o-ring style. just normal style! perfectly matched to the polini 43mm piston

works perfectly with vespa malossi studs or m7 x 125mm polini studs as long as you have a minimum stud length of 122mm you're good to go!

NOTE: this head does NOT have decompression! you will have a harder time trying to start your bike with this head.

fittings are 16mm OD, 15mm ID.

Please note when installing the fittings you should position the fitting in the direction you desire it to go and then tighten down the bolt. If you attempt to tighten down the fitting and then turn it the seal will be twisted and will possibly not seal. Make sure you follow these instructions carefully!!!!

head diameter is about 114mm and about 28.5mm wide.

water cooled isnt for everyone. make sure you have enough experience before you DIVE in (hahaha i crack myself up)

anyway, this thing is seriously sick. just about as flawless as it can get. MIGHT have a few tiny little pits in one of the fins, but basically perfecto!

enjoy your journey into uncharted territories. just make sure one day, you can amaze your friends and tell them:


  rate this moped part be the first!
