Das Projekt ABS System für BMW 2-Ventiler kann beginnen

Following the increasing number of requests for an ABS system for our SE BMW concept bikes, we have taken up the issue. For the 2-valve bikes with rear drum brakes, we are planning the system for the front brake. As 80% of the braking force on a motorbike is transmitted via the front wheel and a skid at the front is also more difficult to control than at the rear, we also see this as the focal point.


Our advice

SE side stand for all BMW 2-valve engines

The prototype is ready and has passed all tests. A few minor changes still need to be made, then series production can begin. The whole thing doesn't look that complicated on the table. The development and customisation for the various models and attachment combinations was very time-consuming. But the preparatory work has paid off.
The stand solves many problems when using other exhaust systems. The issue of ground clearance on left-hand bends and early touchdown on bobber conversions has also been solved.
It is also used as a replacement for the Paralever models, where the side stand is no longer required once the crash bar has been removed.
The SE side stand can be optionally equipped with an ignition interrupter switch. The function allows both automatic folding and locking in the unfolded state. A stand that can do everythin

You don't always have to do everything yourself. In the case of the crash bars, however, we had to. Firstly, there weren't any available on the market and if there were, the price was upwards of €250. So we fed the CAD program, looked for a good manufacturer and here they are: The SE engine guards for all BMW two-valve models.

SE Footrest comfort installation kit BMW R65 R80 R100 Monolever Twinshock

The original footrests of the BMW R65 R80 and R100 are positioned comparatively far forward. In addition to the unusual seating position, the space between the carburetor and footrest is also very small. In order to create sufficient clearance, BMW has offset the footrests on the right and left by approx. 40 mm. Nevertheless, riders with larger feet in particular bump into the carburetor float chambers when shifting gears or braking.
The SE footrest adapters place the footrests at the same height. We set the brake side back 65 mm and the shift side 105 mm. We lower the height slightly by 10mm to make the knee angle even more comfortable.

Dream or truth?

Dream or truth? The manufacturers' performance data or the desired performance after tuning are always interesting topics for discussion. We have dedicated a category to this topic and published a few performance diagrams from our test bench and our performance kits.
