Awesome.. could you point us to where they've been published?

The information is HERE

It reads "...the Super Monza delivers the following :- Sub power delivery is strong at 20 BHP between 4,000 to 5,500 rpm. Main power is delivered at 5,500 to 8,000 rpm at 30 bhp. The torque line between 5,500 to 8,000 is completely flat at 20 ft lbs."

Here's the graph for the Avanti fitted with a Franspeed Race pipe


Now, I've seen the torque graph for the Super Monza, but if you plot the data roughly onto this graph, you'll see we really are talking about two very different beasties here.

Good link above. As it says on the link, it is very easy to tune for high horsepower (the power tends to get very peaky with a narrow power band, losing lots of power up hills and fighting against headwinds) but to achieve such high horsepower with a fantastic spread of useable power throughout the rev range is a hard act to follow. That is why this is different in my opinion, and you can only get that sort of power by all components (exhaust, ignition, carb, port timings, compression, squish band, reed valve) all working together in harmony.
If other, less expensive kits can achieve 30hp with a wide spread of power throughout the range revving up to 8000rpm and pulling a tv gearbox ,without lots and lots of further tuning.......i'll eat my hat!

Oh and just to add, before anyone says RB250, remember that two supermonzas did the 6 hr endurance race in spain, flat out, without issues. I remember in scootering when testing the big RB that the tester was told to back off when the temp rose to a certain level.
Not slating the RB as they are very good at what they do, just trying to highlight the difference and why i personally think the new kit is going to be such a leap forward.

Is the graph for the Ron Moss kit prior to any jetting work,its very rich in places leaving big drops in power on the graph,

Yes the graph does show somethings not happy. But this was run with am expansion and isn't it designed for a box pipe?

It looks like a great kit! Hopefully it will be the next leap forward in Lambretta tunning.

But they do like the word ultimate!

Not That I've seen, but I have ridden it with a box pipe, being Ron's Avanti pipe, and the Franspeed puts out better power. This kit is also piston ported, whereas the Super Monxa is reed valve

Anyhow, the point is that the Avanti and Super Monza are very different and shouldn't be compared.

the only reason i mentioned the supertune avanti kit is because of the value for money,and the fact that the 'home' tune men can mix and match what they have got previously,
the large estimated cost of the super monza will exceed what the average scooterist can afford (unless your going to offer finance.lol) in one hit,and for that very reason is why i mentioned the supertune kit,
the way that charlies scooter goes ,if the kit performs the same it will be money well spent!

Are you sure that has the Franspeed race pipe on in this graph?

that does look like an expansion pipe graph mate.. i would expect the box pipe to lose the peak and a few hp.
