Novarossi and Axe Rossi are two different companies. Nova being good, Axe being junk IMO.

Yes two different companies, but dont be a fool have you even owned an AXE, good power, longevity, easy to tune and will keep running with a (fat) bad tune.

What more can you ask for.

I am no fool and while I have never owned one I have worked on several. I will take anything made by Nova, OS, Sirio, OPS, or CMB first. I will take them over an SH engine though.

I don't have to own a Yugo to now I don't want one. And like I said, I worked on a few and was not impressed by the quality or the performance. But if you like them, good for you. Maybe you got a better batch then the ones I saw. I will stick with Nova based motors and not worry about having any problems or lack of power.

Well I suppose if Zac Ryan puts his Hong Nor on the podium at almost every race he attends in Australia or overseas then I am guessing that an AXE Rossi is not a bad motor. The backup and support in Australia is excellent as well.

Personally I have seen them with 40+ litres of fuel and still going strong, they may not be as pretty as some of the more expensive motors but I can honestly say that at races I attend and with my AXE motors they just keep running with flameouts an extreme rarity.

+1 im wif you,

wingracer, champ buy one, race one and then make your decision, sure there not as punchy as the RB's and Sirio's but they hold there tune and run really nicely. race/run one before you make your disicion brother!!

I am pretty confident they are not, I don't know for certain though.

nope they are totally different.

for starters, there is no such thing as a nova 21-7K, they only have the 21-5, 21-5K, or the 21-7, and then the sprts variants which im unsure of the code and also the 367 which is their top of the line variant.

On the debate of AXE ROSSI, i have seen several run, and own a very old AXE Black Majic. This engine has barely no pinch and must have seen in excess of 40ltrs (approx 10gal) and it still pulls hard with only the odd flame out.... they are solid motors for a great price here in aus

VSpec, AXE then the STS... an AXE is the perfect beginners motor, easy to tune and holds a good tune.

Axe Rossi and Novarossi are not the same. Both offer low and high end engines. Axe appears to use more older italian design while Novarossi will push newer designs. Both are good choices IMO. I think only the conrods can be interchanged, thats the only similarities.

As for comparison of a Axe Rossi sport and a Novarossi 21-7, that would be similar to comparing the Novarossi 21-7 to the basic Novarossi N21B.

Budget engine, Axe Rossi sport with 2050 pipeset kit. High end budget, 21-7 or comparable Axe Rossi motor.
