Supercharged Motus MSTR Hot Rod | WILD FILE

A blown Baby Block from the boys in Birmingham.

The regular duties of Motus Motorcycles co-founder and Design Director Brian Case have focused on the overall design of the proprietary V-4 engine and recent launch of the MST sport-touring motorcycle (see our exclusive First Ride video here). But Case is also a motorcycling hot rodder who has been burning some midnight oil during the weeks prior to the recent Handbuilt Show in Austin, Texas. The result of his efforts is this special side project based on one of the company's 2015 MSTR sport-touring bikes.

In true streetfighter tradition, Motus Design Director Brian Case stripped away much of the factory parts before adding the Procharger supercharger and 4-2-1 tri-Y stainless exhaust with titanium Akrapovic GP slip-on.
The Procharger and 4-2-1 breaks up near-perfect symmetry. Do we mind? Not at all!

This custom Motus was dubbed "Lone Star 2" during the very short four-week build schedule and was meant to explore some concepts that he has been wanting to try for a while. One of those is the bolt-on supercharger made by Procharger.

The blower required a custom designed bracket and pulley drive system mounted to the left side of the Motus MV4 engine, and it’s driven off of the alternator pulley. Case admits that it was actually very easy to do, proving the MV4 is well suited for custom built applications.

The stock Motus ECU also made an easy job of tuning the system, which already has PC-based programming features to recognize supercharging. Internal mods include a set of dished Mahle pistons (available in the Motus accessories catalog) that lowers compression to 9.5:1. Claimed power output is a modest 230 horses.
