At a time when many Scooterists are confined to their sheds and garages (what a nightmare), SIP wanted to remind us all about their Lambretta crankshafts. They were launched back in 2018, (as featured here) and are available for all Lambretta Li/TV/SX/GP/DL models.
The cranks feature a stronger GP style 25mm flywheel side stub and come in two conrod lengths, 107mm and (smoother running) 116mm – as used in the TV 175. These are also suitable for kits using a reduced 30mm compression height, as opposed to 39mm. The conrods come in a choice of standard or polished finish.
You can find them on the SIP website here.
So far through 900 or so dyno tests both cranks have performed well and remained true which is as good as you can hope for. How these cranks perform long-term on the road is something that I still have to investigate.”
