Mule Arctic Monkey

This bike has been kicking around the internet a while, but it's a great example. This Mule development mule was sold to Arctic Monkeys drummer, Matt Helder.
It has many of the Mule trademarks. Mule triple clamps; Fireblade 954 forks; Works Performance shocks; Mule seat and tail; Kosman front hub and a Red Devil brake caliper (I'd never heard of them, Red Devil specialise in car brakes); 904 big-bore, exhaust; modified stock carbs. It's running on 19s with race tyres, unusual for Mule, he fits 18s more often.
The bike also has the clever lower frame rails that contain oil and do away with the need for an oil cooler. This modification was developed for the Streetmaster (read all about that incredible Bonnie in Sideburn 8). G

Streetmaster Race Bike - EXCLUSIVE

The Streetmaster, built by Mule, is the high water mark of street tracker's, the one all others will be judged against. And now there's a race version, tested at Perris, California. Exclusive news from Mule himself...

Richard Varner who IS Streetmaster decided we should build a race bike to showcase our chassis and other parts soon to be available. So that's what we did. Racing intent is start out locally and see how it goes with the strong possibility of bigger things later this year.

The motor has the 270 degree crank with the total emphasis on traction and torque. Weight is very low (I plan to get it weighed this week) and handling is neutral and superb according to test pilot Pro Jeff Johnson. Power is good and more dyno work, gear sorting and refinement will take place over the next couple weeks. All in all, a great first outing with perfect weather. More to come for sure.

So-Cal Streettracker

This is some kind of collaboration between Streetmaster (who built their first bike in conjunction with Mule) and hot rod/dry lake royalty So Cal Speed Shop. Lots of nice details, but the pipes look unnecessarily noisy. The spec is the same lightweight chassis (as developed by Mule, we believe) and tuned and lightened motor with a big flatslide. The alloy sidepanels and tail are a nice change from the norm. Slimmed down clutch cover is neat too. G

Mule Streetmaster details

Weeks ago I said we'd show you more details on the Mule Streetmaster. Here they are. Sorry for the delay. G

Richard at Mule has been drip-feeding details of this bike for a few months now, but swore us to secrecy. Ben nearly let the cat out of the bag last week, but here is the official word. If there's anyone building better street trackers anywhere in the world (except perhaps Jason, but he doesn't do them to order) we'd like to know about them. More detail shots later today.

This is a prototype for a production run of streettrackers called "Streetmaster". A longtime Triumph enthusiast/rider by the name of Richard Varner decided he wanted to build some lightweight, more powerful versions of the new Bonneville. The prototype is basically a Dirttrack racer for the street except that it's well under the AMA legal weight limit.
Horsepower with modest upgrades is 75 at the wheel and well above the stock 50hp. Weight is in the 305-lb range thanks to the generous use of Titanium, carbon fiber and lightweight components. Pounds of steel were removed from the crank for a large dose of riding excitement! Motor work was carried out by Charlie Barnes and the chassis designed and built by Mule.
The brightest jewel in this setting has to be the billet primary cover which took months of development and buckets of dollars to fully iron out. But finished in a black wrinkle powdercoat, it turns the left side of the engine into the one that gets the second looks. An ignition cover is still in the works.
Final details are still being worked out as to pricing and how many will be available for purchase. Engine components will also be featured on the menu to install on stock or modified road bikes. www.streetmaster.net
