RCR Monoposto powered by Motus Baby Block KMV4 engine

The beautiful red racecar you see above may not be what you think it is. It's not vintage, it has never actually seen competition, and it's not from Italy. What it is, though, is the wrapper that debuts a new powerplant from the crew at Motus, the small-scale American motorcycle manufacturer from Down South in Alabama. It was built by Race Car Replicas from Fraser, MI, and we think it's pretty darn awesome.

The beating heart underneath that sinewy bodywork is known as the Motus Baby Block MV4. This pushrod engine, with design help from such well-known engine builders as Katech and Pratt and Miller, and more recently Mast Powertrain and Performance Design, has been tuned to produce more than 180 horsepower at 8,200 rpm with a wide, flat torque plateau that peaks at 126 pound-feet at 5,000 rpm. Couple that kind of power with the 1,200-pound weight of the 1958 Ferrari F1 replica this particular MV4 resides in, and you'll be welcomed with quite the potential for performance.

Motus isn't yet talking pricing in the public, but is more than willing to hear your plans for its MV4 engine. The bright-red beauty seen here is set to make its public debut on April 11-13 at the Circuit of the Americas track, which, of course, will be otherwise preoccupied by hosting a round of MotoGP racing.

Description: Race Car Replicas of Fraser, Michigan has built this one of a kind vintage replica of a 1958 F1 race car, powered by an American-made V4 engine from Motus Motorcycles of Birmingham, Alabama. Equipped with race-spec disc brakes and a T5 Tremec 5-Speed manual transmission, the addition of the Motus V4 helps turn this 1,200 lb open-wheeled roadster into a real head turner. Packaging the V4 was quite easy, after an adapter plate and flywheel were made to mate to the standard automotive bell housing. Total build time on this project was four weeks. The car will be on display in the Turn 13 area April 11-13 at the Circuit of the Americas for the MotoGP race.

The Motus Baby Block® MV4 is a pushrod-powered V4 that delivers massive torque across a wide, smooth power band. It speaks with an exhaust note unlike anything before it. Equally important, the mighty American V4® uses technology proven to be durable and easy to maintain. It's the same small block architecture found in the most reliable and competitive engines on the planet from popular American passenger cars and trucks to high performance racing vehicles. The Motus crate engines are available now for purchase and are the ideal choice for anyone looking to package a compact, lightweight engine with a factory-tuned power output of 180bhp+ at 8200 RPM and 126 ft.lbs of torque at 5000 RPM.
