I have often seen early BMWs weaving on motorways, I thought it was what they did (the earlier ones)
BMW /5,/6,/7 models don't have headsteadies the engine/transmission are secured to the frame by 2 ,12 mm studs. you can stiffen theme up by trellising the swingarm and replacing the upper fork plate with a much more substantial aftermarket part, which has its' controversies. The majority of Beemer pilots are so enamored by BMW's reputation for reliability that, hem, "extended' oil changes, retorques and various adjustments are more the norm. Norton owners become mechanics within a very short time of winning an owner badge, a Melential, might say something bright on a very metaphysical note: Well, like, that doesn't sound fair; followed by: Have you told FaceBook about this?, like I can Tweet something out to warn, you know, like, other organics....Assholes!!!!
The English, German, Italian and US makers produce products that can do the same job, but with different "DNA".
I have an R100 project that is definitely pregnant, but a long way from labor... It will get a head steady, a Ne Plus Ultra dynamic balance, but it will not get a 336 cam or any form off peashooters, it will be fitted with a set Jim Cray silencers and 40 mm headers, available form Keihan Systems.
All motorcycles manufactured for the general public, with very rare exception, are built to a price point; I build them without such constraints...
Best.
