XS650: Sidecross   Leave a comment

I’m a big fan of sidecross. Motocross with a sidecar. As a youngster (not sure if I have memories of this or if it’s just wishful thinking) I raced amateur motocross. Later I raced speedway and street meets with a kneeler. Branched out into sidecross and even filled-in while living in Canada, ice racing.

Here, I follow the Veteranen Cup. Sidecross for twin-rearshock, aircooled, 2/4 stroke machines, pre 1984 up to 1000cc and min 250kg. Monkey must be at least 16yo and riders age must fit with the spirit of the race.

I’ve been working on one of my best mates. Trying to convince him to become actively involved. I have most of the kit. We both qualify as riders. All 7 of the races are easily reached from here.

Last Saturday my son and I rode the sidecar up to Schotten for the 25th Classic Grand-Prix – Classic solo and sidecar racing. Always a great weekend getting close to bikes you can drool about.

On Sunday my mate and I rode out to Laubuseschbach for the 5th leg of the Veteranen Cup – was a fun day, He’s hooked now, Poor bastard.

Most sidecars in this class are 2 cylinder units using the XS650 power-plant and WASP or EML frames. This year there are other Yams on offer. An XT and a TR1. Some 4 cylinder Hondas, a CZ, a Norton, 4 BMWs and 2 EML Jumbo powered units (2 cylinder 2 strokes (air or water cooled, 1000 and 800cc) developed by EML specifically for sidecross-can easily get over 100hp).

Unfortunately the batteries in my camera were flat after Schottenring and I didn’t have any spares with me. Hopefully better luck next month in Hennweiler.
