When you’re developing new streetbikes, it can be frustrating to be constrained by emissions regulations and a fickle market. For Brandon Kraemer, the senior product development director for Indian Motorcycles, he took his personal Victory Hammer and threw vexing regulations and market research out the window.

“The desire to create Jammer was really anchored in my patriotic spirit for American products and ingenuity,” Kraemer tells us. “In American culture we love our muscle cars, and the Big Three auto manufacturers have proven they know how to make them crazy fast while handling really good.

“But then when you go over to the motorcycle market, this idea of a big American motor in a sporty chassis isn’t as popular, and that performance doesn’t resonate as much with the common customer. So I knew if I wanted to build a muscle-car bike, I was going to have to create it myself.”

Kraemer said the idea started out modestly. He was looking to get additional cornering clearance, stronger brakes, and a more aggressive riding position. A Penske shock with taller links was added, as well as Brembo calipers and dual 320mm front rotors. A ProTaper handlebar was internally wired for a clean look and sporty ergonomics. The motor was upgraded with a 116-cubic-inch big-bore kit.

And then things got really wild with the addition of a Procharger B1 supercharger kit from Lloydz Performance. The incredible result is a stupefying 212 horsepower at the rear wheel, with a ridiculous 182 lb-ft of torque.

Look at those soaring traces: More than 100 lb-ft of torque at just 2,100 rpm, then culminating with 212 horsepower at the top end!

“The bike is a visceral beast to ride,” Kraemer reports. “(Japanese) liter-bikes are crazy fast, but being so smooth, you just don’t realize how fast you’re going, where Jammer makes you feel everything. I’ve never ridden a bull in a rodeo, but I expect that adrenaline feeling is on a similar level!”

Kraemer places most of the credit for completion of his bike to Scott Kietzmann of Conquest Customs, who performed most of the chassis work. Kietzmann was also responsible for the beautiful left-side exhaust that exits under the tail, requiring significant fabrication to the mid-frame and rear subframe to get it packaged within the bike. Carbon fiber bodywork was painted by Rick Corgan.

So, what’s it like to ride the Jammer?

“First off it’s crazy loud, kinda like being at the dragstrip when they start up a Pro Stock car,” Kraemer says. “ Then the next thing you notice is the supercharger noises, which are more mechanical sounding than you expect.

“Then you hop on and below 2500 rpm it’s pretty tame,” Kraemer continues, “but once above that point, the blow-off valve slams shut and it pulls harder and faster than anything I’ve ever ridden. With the GP-style reverse shift pattern, you bang through the gears almost faster than your brain can register it, and before you realize it, you’re well into triple-digit speeds.

“To me, bikes are made to get our adrenaline pumping. And Jammer does that better than any other.”

Jammer’s undertail exhaust dramatically cleans up the right side of the Hammer. Dual Brembo brakes are up to the task of harnessing 200 horsepower.
