The 900 is a factory mod
Not sure how this title has stuck; it's an oxymoron. It's either OEM or been modified, not both. Marketing at it's finest I guess.
There's nothing mythical about this engine. Yes, I get its a "big bore" based on the 850 and Carl had a 900 kit, but really?
Reusing a design and incrementally increasing displacement is something engine makers have been doing for decades, including powersports.
