i've seen more details that are interesting. What i'm wondering is, how come these new techniek is out 'now' and other manufactures are not using it? Will it be as good as they say? Or are the current manufactureres unable to create such materials?

I'm the only one who has done their own investigations and compared it against all other 7 port Novas and other Nova based mills?

Bore/Stroke.
Ninja: 16.27/16.79
Nova RX221: 16.26/16.80
Nova PLUS 21-3C: 16.26/16.80
RB C5: 16.22/16.80

INSANE redline.... 48k rpms!

BTW: Asked the price and seems slightly cheaper than Nova mills. Uses the small crank (14mm). I was thinking on giving retirement for mine RX21's and planning to get one, just for testing.

any one got a price on them yet they look preety good ,shoot maybe ill grab it as a spare for the rb .where are they available anyone got any links

THe outside looks great, but no pics on the inside yet... let's see what that brings....

Is this a Nova Rossi based engine

This engine is built by GRP. I do not believe Novarossi has anything to do with this engine.

Very nice looking motors and Mario Rossi known to be one of the best nitro engines designer in the world.
As motor it self-pretty short strok motor. It should be very high RPM motor ( I am beliving in 45K out of that motors), just one thing I don't personaly understand for 12 MR T01-with parameters stated in their web site strok 13.79 and bore 14.02 the size of the motor come up to 2.13 cc or .13 ci which is over then allowed for IFMAR, ROAR or EFRA rulls for sedan. It ether wrong numbers on their web site or something else, but defenetly doesn't fit to existing rulls (2.11 cc or .12 ci)
here is web link to calculate timing and volums for references http://www.palmarisracing.com/Timing_Calculator.htm

I also noticed that........

maybe bore stroke were confused...........the .21 engiens are the sameb bore and stroke as Novarossi ones.............perhaps the .12 engine is the same as well (stroke 14mm and bore 13.8...................or 14.02 and 13.79 just to be different )................

I am not sure what you guys are looking at but the novarossi .12 has a 13.8 bore which is bigger and a 14.04 stroke which is also bigger and that motor still falls under the engine guidelines..HHHUUUUUMMM........

If you dont believe me than check out this website: http://www.novarossi.com/eng/motori/ns12s3.htm

How can a motor with a smaller stroke and a smaller bore be bigger.... Just a thought................

You guys are using the palmaris calc wrong .... Punch in the a stroke of 14.02 and a piston bore of 13.79...... It is all legal


I know for a fact that web guys sometimes input the wrong info... I would imagine that the motor is more likely to be legal than not....

I was told that the top of the line .21 on-raod engine would retail at around the 400 euro mark.... wicked price if that is so

.

i didn't use the palmaris website cal.............anyway it works..........

just check the info on ninja engine website and do the maths.........

stroke>>> 13.78
bore>>>>14.02

capacity = pi*(14.02)²/4 * 13.78


=>capacity = 0.1298 cubic inch............

anyone got any pics of the internals yet? piston/liner, crankshaft?
found out from my LHS that the ninja engines won't be coming out with modded versions.
so i guess the stock ones might (or might not) be mildly modified from the factory?

hi scott,
wat's the word on the expected release date?
have you seen the engine yet?
or better still, tried it out?

They are expected to be in stores early February, but we'll see.
