Storz SP1200RR | Summa Café Loudly

Why can’t Milwaukee do this?

Harley-Davidson has had 55 years to build a bike like the Storz SP1200RR and never has. (We’ll set aside the XR1200R for now.) In fact, it took former factory dirt-track tuner Steve Storz to conjure the superbly designed and impressively built conversion parts to create a bike like this—a potent mix of flat track and café racer style and performance.

Impossible you say? Yeah, maybe on the track where top riders in AMA Pro Racing’s XR1200 class lap about six seconds slower than the entry-level Supersport 600s. But the street isn’t the track, Scooter, and every little knife-edged advantage that’s essential at Rattlesnake Raceway isn’t actually necessary to dispatch vermin at Deals Gap. Besides, on the street, looks, vibe, and cool are, well, cool. If you don’t believe it, check out the hipsters on their primer-black $1500 café specials and see what kind of action they get. OK, maybe you don’t want to know about that. But the point is, presentation does count. And the SP1200RR has it—big time.

The SP1200RR is the latest in a long line (since 1990) of Sportster-based specials that Storz has patterned after the iconic Harley-Davidson XR750 dirt trackers and road racers. To build one of the most inviting Sportsters ever, Storz starts with a Sportster 883 or 1200 from any Evo generation (including 2003 and earlier solid-mount engines, 2004 and later rubber-mount engines, and 2007 and later fuel-injected and rubber-mounted engines). He keeps the core engine, chassis and electrical essentials and then upgrades the rest using premium components. Every bike is built to order starting with your donor bike, so you can pick and choose your level of play.

If the donor is a Sportster 1200, the powertrain remains stock. If it’s an 883 model, like the 2007 XL883 Standard-based bike shown here, it gets a 1200cc upgrade using Wiseco 9.5:1 compression-ratio pistons and a re-flashed ECU. A minimalist Performance Machine air cleaner rides just above big, satin-black, XR750-style Storz by BUB up-pipes with 2.25-inch ceramic-coated tubing, while the belt gives way to a #520 chain-drive conversion with modified PBI and Talon sprockets.

Gone is the stock Sporty fork, replaced by a proprietary Storz/Ceriani inverted piece. Out back are premium Öhlins HD144 14.25-in. piggyback shocks. Eighteen-in. black Excel rims, married to H-D hubs and stainless Buchanan’s spokes, carry Metzeler Marathon tires, 130/70 front and 180/55 rear. Brake upgrades consist of triple Galfer DF680FLW petal- discs and beefy Performance Machine four-piston calipers.

Controls include Driven clip-ons, modified to Harley-Davidson’s 1-in. standard, Performance Machine switchgear and grips, Storz rearset controls and a Storz hydraulic steering damper. The pièce de résistance is the unique bodywork, starting with a handmade aluminum Storz gas tank with SP1200RR emblems and then adding a twin-pad Harley-Davidson roadrace-style solo seat and a minimalist Buell front fender, in this case all painted by Bill Kee of Vintage Restoration in nearby Oxnard, Ca. The stock hooded headlight and speedometer remain, keeping the Sportster heritage alive.

Motorcyclist intercepted the SP1200RR as it was arriving for exhibit at The Quail Motorcycle Gathering in Carmel, Ca, last May. And with photographer Jeff Bushnell’s orienteering, we quickly headed into the local mountains for a good, long get-acquainted session. With its twin up-pipes, spare lines and orange, white and black paint with silver stripes, the bike definitely has a persuasive profile. But it doesn’t take long to get exposure to a dose of Sportster quirkiness after stepping aboard. For starters, the air cleaner fouls the right leg slightly. Then there is the unmarked switchgear, which takes some memorization to recall which button is for the starter and which two are for the turn signals. [Although you could always label them.—Ed.] But as they say, love overcomes all (except for infidelities with the nanny). In the big picture, these are minor issues.
