Watching your old motorcycle heading down the road with its new owner, you count the cash and stuff it in your pocket, you should be happy, right? Well, sometimes, not so much, especially when you remember what a great bike it was, so now what? Well, if you’re Stellan Egeland after you just sold your Harrier, you build another one, only this time you decide to make it simpler, … of course, plans evolve while you’re building and you end up with another really sweet bike, the Slugger, only this time, it’s a rider, it’s not for show and it’s not for sale.
Stellan tells me he started out with the 1200 boxer engine from a BMW HP2 Sport. Nice engine, but he thought a bit more power might be nice so he modified a Mitsubishi turbo and installed an intercooler where the tank usually sits inside a carbon fiber scoop to point the air in the proper direction. The fuel now sits in the enclosed area under the seat. He fabbed up the exhaust to the turbo in stainless and the exhaust from the turbo, including the muffler, from titanium. JE pistons and a Link G4 Atom ECU top off the engine treatment. The result is 202hp and 153 foot pounds at the rear wheel. That should do it.
All of that new power goes through a BMW 6 speed, but Stellan says the original swingarm on the HP2 has a nasty wheel hop problem on downshifts so he made a new one with better geometry mated to Öhlins suspension and the combo works great.
The front hub steering setup comes from ISR along with the front and rear brakes and hand controls.
The frame is made from 2391 steel tube.
Wheels are BMW as are the lights. Except for the carbon fiber and milled pieces, everything else is Stellan’s handiwork.
Dry weight is 381 pounds and with a 143 pound rider, weight distribution is 50/50.
All the work was done during 5 months of evenings and weekends. Hmm, … I don’t think 5 months of work in most of our shops or garages would result in anything like this. Must be the tools, what else could it be? With so many BMW customs popping up like we’ve seen recently, I have to think there are some folks over at BMW who are all smiles. Makes you look at BMW with a whole new appreciation for the possibilities. Nice work, Stellan!
