Stock replacement rising rate springs
Internationally well known for their sportbike and streetbike suspensions, Dutch specialist Hyperpro has had Harley-Davidson (and more recently Indian Motorcycle) model-specific suspension applications in its line-up ever since the company began in business in 1993.
Their range includes stock replacement and performance upgrade rear shock absorbers and rising rate/progressively wound shock absorber springs, front suspension springs, full front end suspension kits and one of the best known and most widely used steering damper programs in the market.
Seen here, springs are where the company started, and they still regard their front fork and rear shock absorber spring sets as a core competency.
Hyperpro rising rate progressive front fork springs “provide your bike a lot of comfort while riding, a shorter braking distance and prevent the bike from bottoming out,” says International Sales and Marketing VP Jan Belder.
“Together with the specially formulated oil that comes with the springs – an oil that is blended to our own precise requirements – we create better controlled damping, which results in a much more comfortable feeling while riding on the straight and while cornering. It is all about confidence and consistent, reliable and predictable response.
Our rising rate progressive rear spring sets can be mounted on the original shocks for a hugely noticeable and immediate improvement. Due to the rising rate design of the springs, they also give a comfortable feeling in all conditions and riding circumstances, from the wet to the dry, solo, two-up, with or without luggage, the spring rate will automatically adjust for every need of the suspension. Together with a set of progressive front fork springs, it gives the bike its needed balance and much more stability.
Hyperpro front fork and rear shock absorber springs are available for Sportster, Dyna, Touring, VRSC, XR and Street models. The company has 25 employees, a 10,000 sq ft (1,000 sq m) facility at Werkendam in southern Holland, and is exporting to more than 40 countries around the world.
