Share this Article

Recently, we reported about the production versions of the Motus MST making its long-awaited appearance at Laguna Seca MotoGP. But that’s not the only bit of news coming from the Motus camp. The company will also start selling crate engines of the V4 “Baby Block” used inside their sport-touring motorcycle.

The LS1, and now LS7, V8 engines are as ubiquitous outside the Corvette as they are in them thanks to the availability of crate engines. Motus is following in that all-American hot rodding model, selling V4 crate engines for the end user to get creative in its application. Essentially one half of the LS7 V8 engine that powers the Chevrolet Corvette, here are the specs on the $10,220, turnkey, 1650cc (100ci), liquid-cooled, cast aluminum, pushrod, 90-degree Baby Block V4:

  • Cam-in-block, with two overhead valves
  • Splayed lifters for maximum valvetrain stability
  • Aluminum cylinder heads with splayed & canted valves for maximum flow and combustion efficiency
  • Automotive-style low mass, low inertia roller rocker arms
  • Maintenance-free hydraulic roller lifters
  • 4340 forged steel I-beam connecting rods
  • Three-ring forged aluminum pistons with moly coating
  • Wet sump with integral pick-up, serviceable screen and magnetic drain plug
  • Four-bolt main bearing girdle for maximum strength and durability
  • Cast 4340 one-piece crank with automotive-style plain bearings
  • Gerotor oil pump, integrally cast internal water pump
  • CFD optimized, precision cast water jackets
  • Closed loop 250kBd multi-point fully sequential fuel injection
  • Ride-by-wire w/ electronic throttle control (ETC)
  • Cast individual runner manifold with four, 40mm contoured bore downdraft throttle bodies
  • 12 bolt bellhousing (9.5 – bolt circle) for easy application adaptation
  • Spare bosses for alternate accessory drives and motor mounts
