Suspension Technologies Ships High-Tech Performance Shocks for the Harley-Davidson Roadster™

Suspension Technologies, a Yelvington Company, announced today they are shipping their Black Hill Series® shocks for the Harley-Davidson Roadster. Suspension Technologies is the only shock manufacture to dyno test each shock set before they are shipped to customers to ensure the performance profile of the shock.

A Suspension Technologies performance shock is built with premium components in a design so that it significantly out performs stock and increases the capability of the bike including, stopping, accelerating and turning. In addition, because it is designed for the Roadster, it will reduce fatigue and improve the rider’s satisfaction with the motorcycle.

Using his racing connections, Mike Alex, Suspension Technologies’ Shock Specialist, sourced the best American shock components including rods, bushings and seals and applied it to the tried and true racing-oriented performance designs that he had been working on for over the last twenty years.

“Our shocks are making Harley-Davidson motorcycles great again by taking their low performance design and exchanging it with a Suspension Technologies’ high-performance Black Hills shock system,” explained Alex. “We balance the valving between the piston and the base valve and this allows us to get more dampening out of the base valve and deliver a more consistent, plush and comfortable ride.”

Each one of the Black Hill Series shocks for the Harley-Davidson Roadster is manufactured to a strict standard to deliver the optimum damping for the bike. To ensure consistency, each shock is hand assembled, dyno tested and matched to 2% of dampening force. The preload is adjustable and requires no special tools.

Another technique born of racing is the utilization of low pressure nitrogen gas in a monotube shock. This enhances the comfort of the bike because it provides a more linear transition from compression to rebound. Conversely, utilizing high gas pressure can become a defacto gas-spring which can be difficult to tune.

The combination of a strong engineering staff with the in-house CAD design and CNC machines allows the firm to deliver the highest quality motorcycle parts and accessories available today.

Each shock utilizes aircraft-quality 6061 T6 billet aluminum components, which are powder coated for long term durability and good looks. Shocks are provided in midnight black, show-quality chrome or a combination.

The Black Hills Series’ Roadster shocks are available from your local dealer or directly from Yelvington.
