Hodgespeed let us know that SIP is currently in the process of making tooling to produce Vespa smallframe PK-style engine cases. Great news in itself, as they’d gone out of production, but to me, the interesting part of the post is the CAD drawings of the mold for one side of the case. You hear a lot of people saying “Why don’t they just make….” Here’s the answer, look at the complexity and SIZE of that mold, and that’s just for one case-half (engine cases having two halves, you see.) So knowing that SIP has invested tens of thousands of Euros already, with all the machining and production costs to come, and testing, and the concern that the demand might be less than anticipated, or any tiny mistake in engineering or quality control could be disastrous, it’s a wonder they’ve taken on the project, though I’d wager most scooterists are certainly glad they did.
Now, a note, because everytime I post something like this, I get emails once a month forever from non-english speakers: 2strokebuzz does not sell this or any scooter parts. If you are interested in this product, please contact SIP in Germany.
One thought on “SIP to produce smallframe cases”
Would be cool if they weren’t the last one on the bandwagon. GP One does CNC’d Smallframe Engine Cases and Seigiorni also produces casted Quattrini smallframe cases.
