@Stefan @Mike
first, both engines are good and powerful out of the box. often is just a question of the price and the opinion which you like more.
then, you canīt compare german and us prices. normaly the prices in germany are a little bit higher than the rest of the world.
Here the German prices:
MR12 engine only: 255 Euro = 355$
MR12 engine motorbox: 329 Euro = 433$
Plus 12-3 only: 289 Euro = 380$
Plus 12-3 with EFRA 2630 and short manifold: 366 Euro = 482$
At the moment, Ninja is unbeatable for the prices and that are the normal shop prices.
