BMW R100RS “Sixdays” – BikeBound

Rind Efficiency’s ISDE-inspired BMW scrambler… 

The Worldwide Six Days Enduro (ISDE) — recognized till 1981 because the Worldwide Six Days Trial (ISDT) — has been held yearly since 1913, testing nationwide groups of the world’s greatest off-road riders in what’s come to be often known as the “Olympics of Motorcycling.”

In 1964, Steve McQueen famously competed on the primary US nationwide group organized by the legendary John Penton, and immediately, the ISDE attracts groups from greater than 30 nations, with riders masking upwards of 1250 miles over six days whereas finishing up their very own motorbike repairs.

Not too long ago we heard from our pal Robin Ludwig of Germany’s Rind Efficiency, who’s put most of his bike-building efforts into machines constructed for the tarmac: cafe racers, supermotos, and avenue trackers, which enhance his steady of sizzling hatches, coupes, and saloons.

Nonetheless, Robin discovered himself wanting one thing he may journey for longer distances and extra diverse terrain. The result’s his newly accomplished 1982 BMW R100RS “Sixdays” scrambler, impressed by the classic enduros of the ISDE:

“Since I’ve already constructed numerous café racers, I needed to construct one thing else that was extra snug, which it’s also possible to journey in on a regular basis life, however nonetheless draw a number of seems to be 😜.”

The BMW boxer twin “Airhead” platform could appear ungainly for the bogs and woods of the Six Days competitors, however BMW themselves fielded a manufacturing unit group in 1979:

“The purpose of the Bavarians was to carry their 800cc BMW GS 80 right down to a battle weight of 150 kg (330 lb.), to keep away from hopelessly overextending a rider bodily. They then achieved 135 kg (298 lb.) and are proud that this stringent weight discount, hardly believed potential, will be the idea for achievement within the ‘elephant’ class.” –Pace Monitor Tales

For his half, Robin didn’t want his 1000cc R100RS fairly that gentle — only one that may very well be ridden comfortably every day or on longer journeys, the place quite a lot of highway surfaces and terrain could be no drawback.

Highlights embody a do-it-yourself rear subframe and actual leather-based saddle, an R50/5 gasoline tank that matches very properly with the strains of the bike, and a high-pipe 2:1 exhaust much like the sort seen on among the BMW Six Days enduro machines.

The bike is larger than inventory with flat track-style handlebars, giving the pilot a commanding but snug driving place, whereas the 1000cc engine — with the identical exterior dimensions because the smaller displacement flat twins — makes cruising a breeze. Says Robin:

“It’s a motorbike that you are able to do so much issues on and journey longer distances comfortably in comparison with a café racer.”

Amen to that. Under, we speak to Robin for extra particulars on his BMW “Sixdays” scrambler.
