For over 15 years MRB have been at the forefront of improving the Lambretta crankshafts. Over recent years we have grown tired of sorting out problems with other manufacturers crankshafts - from Indian cranks with poor big end bearings and conrods, to Italian made cranks prone to cracking around the big end area or just badly machined to UK marketed cranks that often spin out of line at tickover or come loose from the supplier. We took the plunge and put our money where our mouth is and had a range of crankshafts made for us in the United Kingdom. Made to our design by Alpha bearings, a company at the top of the crankshaft manufacturing game our GP type cranks are available in 58 and 60mm stroke version. They are fully balanced and nitride hardened. They come in various combinations - just the crank, the crank with the packing plates or the crank, packing plates and bearing kit.
