The right hand switchgear assembly is complete with a single-pull throttle rotor for the 1975 Norton 850 Commando MK3 and 1981-1982 Triumph T140ES electric start models.
The Sparx reproduction of the 187SA-type 35317 switch console controls the main beam and pilot lamp circuit, the engine run circuit, and the electric starter. Comes complete with throttle rotor.
The switchgear is used on the right hand side of the handlebar and houses the single-pull throttle rotor. For use on electric-start models only.
The switchgear is clamped to the handlebar with screws and locates the master cylinder assembly to the handlebar.

Do not buy this! The body doesn’t fit the 7/8” contour of the handlebar without significant filing. The master cylinder housing doesn’t fit on the Sparx housing without significant filing. The connectors are different than what are on my bike. The throttle grip eyelet doesn’t have enough material so mine just broke. Soldering of the internal wiring broke. The bolts that hold the master cylinder to the sparx body are different thread size. This product doesn’t even warrant a one star

Hi Ben,
Thanks for your review and we’re sorry to hear you had trouble with this switch gear. We’ve sold a slew of these, and this is the first we’ve heard of these challenges – it sure sounds it was giving you a hard time.
While 7/8″ handlebars are stock on most Brit bikes, we know that it’s possible that the respective contours on your bike are actually a bit larger than 7/8″ in some spots. As far as Brit bikes go, whenever fitting reproduction, OEM or NOS, fettling is always needed. Even bikes coming off the original assembly lines had additional workers waiting to fix the bikes so they would actually run. The good ol’ days.
The product you ordered has bullet connectors as shown in the photos. If you happen to have pin connectors, you would definitely need to change out the bullets on the switch gear wires for pins. These are intended for more than 1 application, and it may be that a Triumph uses bullets and a Norton uses pins (and vice versa!).
Whether made from metal, plastic or wiring – also handle motorcycle parts with care and use the recommended settings for installation. Just like over torquing bolts can cause issues and breakage, pulling or crushing wires will cause wires to break from the solder weld.
We understand that you had trouble with the bolts as well. Because these are black anodized bolts there may be some residual material on the threads. We always recommend lubricating them with an anti-seize compound to make the installation easier.
Again, thanks for providing your experience with this item.
