Gearbox Kit CasaPerformance 5-gear Cyclone 5 Pro gear box 5-gear Cyclone 5 Pro gear box for Lambretta 125 LI/Special/GP/DL/150 LI/Special/SX/GP/DL/175 TV 2°-3°/200 TV/SX/GP/DL for tuned engines Most geared scooter fans have wished for an extra gear at some time or another. At least one more that their traditionally geared four-speed ride can provide. Tuned motors benefit from additional ratios being added to effectively convert their extra power into an increased top speed and reduced gaps between the gears. A close-ratio gearbox offers these advantages and the original Lambretta versions were known as the 'Pacemaker' and 'Close-ratio' transmissions. They solve the problem of the gaps between the gears being too large, but also reduce the available speed range. Either the top-speed is too low, or the revs required to get going in the first place are too high. This 5-speed transmission kit, from CASA PERFORMANCE, provides a solution. The gear ratios are close enough to enable a constant acceleration while changing up through the gears. The overall range of these gears covers the speeds available by using the original 4-speed transmission from 1st to 4th, almost identical with the gears of the DL/GP models engine. This makes it possible to pull briskly away from the traffic lights without incinerating the clutch, while also allowing an acceptable motorway cruising speed at a modest rpm. The team at CASA PERFORMANCE were not only concerned with providing useful gear ratios, but also the more basic challenge of fitting a 5-speed transmission within the confines of a standard Lambretta gearbox. This problem is usually solved by making the individual cogs much thinner, to squeeze five gears into the space normally occupied by just four. The 'Cyclone 5' transmission however, is made up of cogs that are almost as thick as the originals. This has been enabled by maximum exploitation of the available room in the existing gearbox. To ensure enduring employment within the more highly-tuned engines, CASA PERFORMANCE have managed much improvement as far as the production quality and standards of such conversion kits are concerned. This involves electro-polishing of the gear cog flanks, an advanced process that makes their surface especially durable. We recommend a primary-drive ratio of 18/47 or 19/46. The individual gear ratios are: 9/45, 12/41, 14/38, 16/36, 18/35. The kit includes both a strengthened selector spring and a selector spider. Conclusion: The 'Cyclone 5' was extensively developed, adapted and tested during its conception in race engines pushing out up to 50PS of power. The result represents true progress, in this field, for motor dynamics and enduring reliability. 5-speed / High-end tuning / Casa Performance / Lambretta / Strengthened spring / Electro-polished. SIP - TIP: It is essential that all gearbox parts are checked for correct distancing before mounting this kit. The selector forks and all other moving components should be in full working order with minimal play.
