Modern Vespa

So basically from my understand (correct me please if I'm wrong), if I purchase a IT625PRO variator from J.Costa for mine 2022 500HPE I'm good, right?

Now, continuing this line of thought, the masses should be the ones that comes standard (if I read correctly are 31mm x 22g), even though most of my use is in hilly and downhill areas (70%) and highway (30%) to achieve a balance between top speed and starting, or reduce a little to maybe 21.5g or 21g?

And don't change anything else in the clutch or other areas, correct?

In case anyone is interested, after insisting a lot with J Costa tech, I had an answer regarding why they say that their Variator does not work in HPE (500 higher than the year 2020).

I'm posting the translated answer from J Costa to my question if there was any difference on measures between pre-HPE and HPE:

"It is not about measures, but rather a matter of Euro 4 and Euro 5, so in our case, we must make a new variator so that the benefits are adequate."

It sounds to me that the only reason is to lower performance so that the bike can continue to be Euro 5 compliant, nothing else

The same reason that the Acrapovich exhaust is diferent

yasuni has dyno graphs on their site for some bikes now.
for 300, bv350, tmax 500, tmax 530, bmw c650 (holy heck, big gains)

Nope sales talk a exhaust on a stock scooter won't do anything a bigger exhaust on a scooter will loose about 1 HP like the a Akra for the mp3 tested on a Dyno with a stock exhaust 400 on rearwheel 21.9 HP with a akra 20.7 hp

the dynographs are legit. but they are for their jcosta, style variators. I do back to back with exhausts too. havent seen one gain yet. stock always works best. as far as variators the bmw 650 picks up monster hp on the graph and I beleive it because the 300 and 350 barely pickup anything. my silverwing 600 is an absolute monster with the jcosta. and unreal smooth. something a malossi/polini variator cant match.

Vario's won't increase HP a clutch and vario are behind the Cylinder and piston valves and cranckshaft there the HP's are made not on Clutches and Vario's you won't get more HP when you add 32"rims the speedo will say driving 200miles a hour but it is still tops 95 ish on top downhill

plenty of HP are lost between the crank and the wheel. Different vario etc could result in less loss

No the loss comes from the belt not from the vario it won't increase HP

Only thing a Vario or clutch change will bring is an other pickup point on RPM HP will be the same its still 41 BHP on the crank for a 500, 44 for a 500 HPE and 32 for a 400 22.7 for the 250/300

Did these test on the same dyno way back in 2009/2010

A mp3 400 got 32 at the cranck 22.7 at the rearwheel tested on a dyno that you can set for a CVT important
Do it on a dyno that is set on for a geared bike then a CVT bike will gain a lot of power about 45 on the rearwheel because wrong messurement

Same Dyno Runs done as set as CVT
A mp3 400 with different weight rollers still got 22.7 on the rearwheel
a mp3 400 with Dr Pulley SR2517/8 17 gram still got 22.7 on the rearwheel
A mp3 400 with Jcosta first gen still did have 22.7

same dyno on my 400 changed in to a 460cc 44.1 on the cranck and 36.3 HP on the rear wheel with a rapidbike and worked head intake and outlet ports bigger this option did cost me about 5000 euro's finaly at 48 hp on the crank and a engine that lasted no more then a year

Did this one not long ago for a friend
500 ie ABS ASR 41 HP crank 34.3 on the Rearwheel change the stock Throttlebody for the HPE one 44 crank 36.5 rearwheel so 2 HP will cost you about 1000.- euro installed the 0.2 hp more could be outside temp different mixture, thinner gasket, but 0.2 is nihill in increase pick 2 same engines and there will be some differents between them
