they have put post on there page saying they have nothing at all to do with the five speed box now but had thought they were going to be the uk stockist
very strange, as i had been doing a search on the cyclone and came up with Parrspeeds facebook page which had some new information including the first i had heard of a version 2. this was before the dedicated website was running, when i returned to it the info had disappeared.
Latest update from 100mph lambretta club:-
29th October 2012
Having tested a ‘Cyclone 5 Speed’ gearbox and realising that THIS was the ‘missing link’ needed for unleashing the true potential of the Targa Twin engines, we thought it best to try it in something different which would appeal to the masses. Therefore today we have done a ‘before and after’ test with a TS1. The Lambretta in question, an SX200, is fitted with a standard TS1 cylinder, a Mikuni TMX 35mm carburettor and a ‘JL3’ exhaust. Just to make things even more difficult for the ‘Cyclone 5 Speed’, we decided to fit a standard 2.5kg electronic flywheel.
BEFORE
The gearbox was an SX200, with 15/46 primary sprockets giving a 4.82 final drive ratio in top gear. Driven through the gears the build up of speed was fair - but to try and appreciate good 4th gear acceleration, it had to be hammered to death in 3rd gear before changing into top gear. If the scooter was ridden into a head wind or hit a hill, it was problematic. When you got into the powerband in 4th gear, the top speed was good but getting there was such hard work. To sum it up, it performed a bit like an old diesel car. In other words it was a reasonable, steady ride but it was never going to be ‘exciting’.
AFTER
We then fitted fitted the ‘Cyclone 5 Speed’ gearbox and opted to use the actual gears as they are provided in standard form (we have different, optional 1st and 5th gear cogs that all inter-mesh with the same Cyclone gear cluster). We used the 35T 5th gear and 19/46 sprockets, giving a final drive in top (5th) gear of 4.71. From the word go it transformed this engine! Acceleration was great through EVERY gear and from 4th to 5th gear it just felt so close. Pulling 5th gear was superb: it was there to use as an ‘accelerating gear’ and the engine didn’t have to be worked hard in 4th before changing up. We suddenly found that we had a top (5th) gear that was easy to get to and was pulling taller gearing than it had ever done before (remember we went from a 4.82 to a 4.71 top gear ratio). If the engine had been geared to 4.71 with the old four speed gearbox it would simply have never got into the powerband and just plodded along forever. Also driving into, and around, corners, only a change down to 3rd gear was needed with the Cyclone. Using the 3rd meant easy, constant acceleration out of the corner - instead of having to be right down to 2nd, which is what was previously required on the same corner when using the old four speed. And all this while still running the heavy flywheel – amazing! If an intermediate weight flywheel (1.8kg) had been fitted I’m sure even longer gearing could have been pulled quite easily.
CONCLUSION
Not only did the Cyclone-fitted Lambretta have a much higher top speed and much more acceleration, the general ride was so, so much easier. When cruising at 50mph the revs were now much lower, all of which equate to better fuel economy and less stress on the top end. If I wanted that ‘extra’ acceleration, it was there immediately to use. No more thinking about an overtaking manoeuvre - just do it. To sum it all up the Lambretta was transformed from an old ‘chugger’ in to a superb sports bike and the most amazing thing of all is that no increase in BHP was needed to achieve this change. The ONLY thing to make this difference was the fitting of a ‘Cyclone 5 Speed’ gearbox. Trust me you need to try it out: I GUARANTEE you will not be disappointed.
PERFORMANCE FIGURES (ALL QUOTED IN TOP GEAR)
BEFORE (4th gear)
50 mph = 4900 rpm
70 mph = 6800 rpm
TOP SPEED achieved 76.30 mph @ 7450 rpm
AFTER (5th gear)
50 mph = 4670 rpm
70 mph = 6500 rpm
TOP SPEED achieved 84.75 mph @7920 rpm
NB. Both ‘before and after’ tests were carried out on the same stretch of road. The difference of 500rpm at top speed was simply because with the ‘Cyclone 5 Speed’ gearbox fitted, the scooter entered the power band much, much quicker and therefore produced more revs in the same given distance.
