When American motorcycle upstart Motus Motorcycles first began its undertaking of the Motus MST sport-tourer, the company from Alabama made it clear that its 1,650cc engine would be the centerpiece of the bike’s design. Hoping to build off the tuner culture that developed around push-rod engines in the automotive world, Motus even went as far to say that the Katech-designed KMV4 engine (now without GDI) would be made available as a crate motor for hobbyists.
With the Motus MST nearly ready for public consumption, the American company is making good on its other promise, and has released pricing on its “baby block” engine. At a cool $10,220 of your hard-earned cash, the turnkey 165+ hp V4 motor can be yours (along with the engine’s ECU, ride-by-wire intake, engine harness, and fuse box). A pricy sum for the small peppy engine, pricing on the Motus Baby Block at least puts the $30,000+ price tag of the Motus MST in perspective.
