As a motorcycle rider one thing is sure, that once you've experienced a taste of performance and ability in a motorcycle it becomes more and more important. To be sure of a machines capabilities allows the world to open up. When you know you can get on a bike and ride 500 miles in a day and there are very few other machines on the road that compare is empowering. We exist and thrive in the custom world of machines and in this work there’s one consistent thread. Always improve. With this bike I chose to build a rocketship. We are running our Kraus Dynamoto Inverted Front End with Ohlins forks and Beringer Radial Brake Calipers. This bike doesn't only handle amazing but it goes fast, and stops with extreme quickness.
I knew the Dynamite motor needed to be something special so I called on my friend Dave Bozzie to work his expertise. With the help of Feuling Parts, S&S Cycles, and Delkron Dave set out to build a high revving snappy 107”. We Took almost 4 lbs out of the flywheel, polished, welded and balanced it. Keeping the stroke stock Dave added displacement with bigger cylinders and pistons. Feuling Parts provided one of their complete Bulletproof Geardrive Cam Chest kits, Beehive Valve springs and Titanium Keepers. The Heads had about a weeks worth of work in them. All the magic tricks! The motor revs to 8000rpm with a very smooth climbing torque curve. There’s a power band hit at 4,100 RPM than pulls your neck back. The motor was built to compliment the handling and overall geometry of this Dyna. The Carbon Fiber BST wheels make a huge difference with spin up and braking. They really make the bike feel and act very light. We machined a one off Billet Trellised swing arm out of 7075 aluminum that sits at a steeper angle and adds about 2 inches of height in the back of the bike. This increase gives a lot of ground clearance and steepens the neck angle to improve agility and corner ability. The fully adjustable Ohlins shocks suck up bumps and stabilize the rear end of this beast nicely. Of course up front we are running our Kraus Dynamoto Inverted Front End with Ohlins forks and Beringer Radial Brake Calipers. This bike doesn't only handle amazing but it goes fast, and stops with extreme quickness. I’ve done some big road trips on this bike already, usually making sure to find the windiest roads to travel on. It handles the big open highways like a big bike should but also pitches into the corners with ease and confidence. It tracks very well, I have not found any ill handling issues. The bike is tight and crisp and does not have any of the sloppy feeling of a harley. As far as I’m concerned the bike does everything it was intended to do with flying colors. Total success!
The raw metal bronze finish of the frame will change, darken and naturally patina with life. The raw aluminum sheet metal will take on different shades as it oxidizes and the owner re-cleans and re-polishes it. The weld joints in the stainless parts will change color with time. Dirt and oil will find its way in and live in those hard to clean places. Achuma was built with the intention that age would set in. That the battle scars of real road use would take their place and give spirit to the machine. Achuma will never be the same, always slightly changing. The key is that with these changes the owner holds an experience and memory. It is why someone has Kraus Motor Co. build them a machine like Achuma. Just for the experience.
A classic feeling, but aggressive and full of performance. Vintage styling but with modern engineering and high performance products. Light but solid and strong Achuma is ultra maneuverable, with a lot of suspension.
