I assume the levers for the Vit and Svart are the same. I’ve got a pair of almost new shorty levers in titanium color I installed on my Vit for literally a week before I ended up with an upgraded Brembo master cylinder that came with it’s own lever. I’d gladly sell these for a reasonable price if anyone wants them.
Aftermarket levers for the Svartpilen 701 are hard to find. Some suppliers list levers for the Svart, but you actually get levers for Vit. They are not the same and will not fit. Don‘t ask me how I know. So far the only fitting ones I know by a Svartpilen owner are from https://www.probrake.de They seem to have the right adapters for the Svarts Magura clutch and Brembo brake master. Haven‘t bought the myself because I don‘t like the design so much.
