APRILIA 50 RX

[rx80-heiza]

Hello guys:)
I´m Patrick and wanted to show you my bike and tho one of my dad. We rebuild them completly this winter. There ar now 2 Corsa Corta engines fixed and on my bike I chosed YSS Shocks because I wasn´t able to drive with the original Corte and Cosso Shocks.
And we raced them last weekend at the 50cc Motocross at Crespano del Grappa ( Italy) I think the 50cc bike are nearly faster then the 80cc ones.

Now have a look
My bike:

Hello Patrick, is welcome. Great job on your Aprilia, you have many bikes?

[rx80-heiza]

Hello Didier

Me and my father have 4 Aprilias and 4 HRD´s but just one HRD is finished

[THIERRY]

You did a great Job on the Aprilia's! Could you tell us about the engines? what kind of Minarelli's do you use?

[rx80-heiza]

The 50cc are both with Corsa Corta engine the 80cc´s are with the Minarelli K6 engine one with watercooled Faccioli Cylindre

[THIERRY]

What kind of carb do you have on the 50's?

[rx80-heiza]

Dellorto PHBH 28 BS
But we will to get a Mikuni working at this engine

[THIERRY]

Easy or rough handling ( for a 50) ?

[rx80-heiza]

If you are able to hold the engine on high rpm´s that the 50cc is still in their power part it´s really great to ride. but if you get under 7000rpm´s there is no possibillity to get fast.

[THIERRY]

The 80 is probably much more easyer , but maybe less fun! How many rpm's you hold at the maximum with the 50?

[rx80-heiza]

The 80cc is easier to control but the 50cc got a much higher fun factor
I cant say it exactly but I think about 13000 or 14000 rpm´s

here a video of the first run of the engine in our garage

That's very high but "normal" for a 50 Corsa Corta , very nice sound. I think , it holds 3000 or 4000 RPM's more than the 80, that can explain why the difference is not so important at least.

That´s tha 80cc is easier to drive on low rpm´s but there would no power over 10000rpm´s and the 50cc you have to ride with high rpm´s. I think that is the reason about the small difference,too

[THIERRY]

Both RX's have the same engine ( Minarelli CC) with the same carb?
