You already know Motus created a really impressive machine for the rider in search of that All American V4 rumble in a very capable yet civilized sport bike, but what if Doctor Jekyll was allowed to break free of his bonds, what sort of brutal Mr Hyde would you get? Well, you might get this, the “Lone Star 2,” a naked Motus MSTR with forced induction and a bad attitude.
The mild mannered co-founder and designer of Motus motorcycles, Brian Case, has a wild streak, leave him alone with a pile of performance parts and he locks the door and gets a little crazy. He stripped away bodywork until he could clearly see the DNA of something a little more raw. A Procharger supercharger was waiting. Brian says:
The blower required a custom designed bracket and pulley drive system mounted to the left side of the Motus MV4 engine, and driven off of our alternator pulley. 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. I grabbed a set of dished pistons Mahle made us for our accessories catalog, lowering compression to 9.5:1.
He bolted on a set of 4-2-1 tri-y stainless exhaust headers with an Akrapovic GP slip-on muffler to quiet things down a little, then he mounted Pirelli Angel GT tires on a pair of one-off 7-spoke carbon fiber wheels made by BST. The result looks positively uncivilized, in all the right ways. Brian estimates output around 230 horsepower.
Brian’s been brewing this beast for the last four weeks and you can see it at the Handbuilt Show in Austin, Texas this weekend. He calls it the “Lone Star 2.” If you happen to be in Austin, you should check out what he’s done, get up close to see all the details, but not too close, this one looks a little dangerous.
And just so you don’t forget what this “Baby Block” V4 sounds like, here’s a little drive by:
