In the past, we had been using Viton seals, which are already very good seals.
Also new is the availability of heavy weight shock oil for sidecar and racing applications. Shock oil option must specified at the time of order.
Scottie's Workshop shocks for /2 were created to address the shortcomings of the current choices: Boges are soft at low speed, but wallow at greater than 65 mph, whereas the Koni's are somewhat the opposite: hard at low speeds and better at high speeds.
Scottie's Workshop shocks for /2 are handmade in California with an aluminum body, Disogrin seals, much thicker chromed shaft, and are fully rebuildable.
The dampening is soft and low speeds and firmer at higher speeds. I have eliminated the "mini doughnut" cushions in favor of a high compliance progressive natural rubber conically shaped bumper.
I have been really pleased with the performance of these shocks on my /2 both around town and on high speed long distance runs. Customers have reported that their bikes feel "like new"!
Each set (2 front and 2 rear) are $800 per set, plus shipping. Call the shop at for more info.
