Everything in there is pretty smooth, but there is no hi-gloss polishing anywhere. The cylinder already comes quite smooth from the foundry; the port windows are hand milled to a template, the exhaust duct and the radius from the duct to the cylinder bore are CNCd and some areas like the transfer duct entries are slightly polishedOriginally Posted by peewee
(click three times on the cylinder picture below to see the surface structure).
The cases are completely CNCd but not polished. In case you were expecting sand-blasting or golf-ball dimpling or suchlike: there isn't any. Only the inner and outer disc valve covers have a distinct structure, but that has nothing to do with gas flow; it serves to reduce the viscous friction.

Frits,
As a non-loaded question, how many 125 RSW and RSA engines were ever produced and what quantities ever got sold to private teams/individuals?

I haven't got the faintest idea Ken. I always kept as far away from commercial things as I possibly could. And so did Jan.

In the Stuff frits posted or on the aprilia web site that Frits linked at some time there is a list of engine numbers for diferent years. A clever man could add them up.

I can't remember where the Aprilia race website info is?
Edit yes I can

In 1989 25 replicas 250's were sold
In 1992 Aprilia sold 40 RSV250's
Around the same time Honda Sold 150 RS250's and 500 RS125
If I take a guess then I would say no more than 125-135 or so 125's would have been made per year?

I wouldn't be surprised if sales went up a bit after 1995 when Jan Thiel joined Apriliaetc...

In 1988 aprilia made 30 250cc race bikes
In 1992 aprilia made 40 250cc race bikes manufactured
Thus I'm sure there after there were greater numbers of units made up until a point when racing numbers began to fall.
How many of each model is made now 2015

Maybe but I think Max won the Championships that year but Max's bike I think you have said had Non Thiel (AVL?) Cylinders if I am not mistaken.I wouldn't be surprised if sales went up a bit after 1995 when Jan Thiel joined Aprilia
Aprilia had won the 125s the year before for I think the first time with Sakata But Honda won it the next two years with Aoki
I do know that in 1993. A Honda RS125 cost 6000 Pounds and An Aprilia Cost 16000 pounds.
Then again none of the Hondas that were competitive didn't have big $$$ spend of cases and suspension and A and B kits. The B kit was 19000 pounds in 1993 so god knows what the A Kit cost.
The ADM cases to also for a cassette box were about 10000 pounds.
Yet a year later the Honda B kit was only 2500 pounds and the RS125 had gone up to 8000 pounds.

I have the paperwork from 1992 when the 1992 model Aprilia 250cc & the 1991 model 125cc upgraded to 92 specs I now own we're purchased. I will look at the costs from back then but I'm pretty sure the 250 was $96,000 Aus dollars. The combined total for the 2 bikes in 1992 was $130,000 Aussie dollars.
125cc was ridden by Allesandro Gramingi or Gabriel Debbia for Team Italia as pictured, note a young Lorris Caparossi in the background.

Sorry all. But how do I rotate the pictures ?

You're right. But I was talking about 'after 1995'.
Which I proudly remember, because Aoki's Team Molenaar bikes were prepared by Hans Spaan, using my FOS dyno hard- and software.Aprilia had won the 125s the year before for I think the first time with Sakata But Honda won it the next two years with Aoki.
Then, after two years of glory, Aoki was relieved by a young Italian called Rossi, using engines, developed by a Dutchman called Thiel.
The A-kit couldn't even be bought with money alone. Honda had to think you were worthy of it.none of the Hondas that were competitive didn't have big $$$ spend of cases and suspension and A and B kits. The B kit was 19000 pounds in 1993 so god knows what the A Kit cost.
The last A-kits went to Team Gresini and Team Molenaar and it turned out that the last B-kits (that had, in contrast to the A-kits, no power valve) were better than the last A-kits. In hindsight, the best part of these Honda kits was their ignition: much stronger than the weak RS125 standard spark box of that era.

Busting all those Aussie stereotypes Rick.
