I owned a Kawasaki W650. The W stood for WOBBLE. Also, OEM and many tires on this bike locked into rain grooves like NO OTHER motorcycle. I had more than 2 dozen almost death wobbles. I think the geometry of the frame and rake contributed to the frequency of the WOBBLE. 55mph, 65mph, 75mph when it would kick in would make you reconsider riding motorcycles. My dozen Honda's, Yamaha Warrior 1700, and HD Sportster have NEVER done the wobble. The saving grace of the W650 was the horsepower was very weak. Had the bike had 70+HP the bike would have been 100% death with ownership of the W650.

I can't really remember the OLD Kanofsaki W650's but I am familiar with the new ones. They seem to have all the bugs ironed out... However they load massive amounts of weight onto the front wheel, so if you go onto SAND - it just ploughs in and washes out....

Like riding a 10 speed racer onto the beach.... front wheel goes straight in - real deep, and over the bike goes.

I also find that bikes are suited to different riding styles. I have a 350 Royal Enfield Meteor cruiser , I also have a Benelli imperiale quatro centra (400cc in English). both great for normal road use but not for sport biking. I notice on a lot of YT vid's the REV LIMIT these bikes out, yet I'm never even achieved that once? both are Classic 1950's general design appearance but have Fuel injection and ABS on both. when I'm riding the Bike does the talking when they both attract a lot of attention, usually from old Guy's who used to ride and actually think they are originals! lol! I'm pretty sure if a Janus is rided to match it's apperance shall we say, they are probably perfectly safe. Also Who rides at speed on a steel grid bridge or scarified road surface anyways? that's asking for trouble from the off. Yuo domn't ride in tramlines either you scoot across them not on them. Same thing

Doing wheelies in most countries is Illegal anyway, in the UK it can be a Ban. Why isd there a need to go on one wheel with a vehicle built to have two on the road. With the wobble thing, tensing up is the worst thing you can do and braking as well just shut the throttle and stay loose,

The issue of speed wobbles, was usually cured by adding steering dampeners.
This is not new and it's been going on - and off - for a long time.

And yes - at 170 Kmh - you sure know it.

The Kawasaki 2 strokes of the 70's were classic for wobbles and they even developed a perpose buit Damper for the bikes the fitted the top of the folk yoke and onto the down frame at the front end, that cured it and it was adjustable as well. In the 70's Yamaha solve the problem with a screw down damper on the head stock you could adjust by simply turning a knob on the middle of the top yoke by the bars. I had plenty of Honda's and don't ever recall the need for dampening?

@mrghoster: Just had an ancient memory..... many motorbikes going back to the very beginning in the 1910's etc., onwards, had frictional steering dampeners... The Vincents had them too... "Steering Damper: Very often one finds the Vincent damper plates greasy from over-use of the steering head grease fittings. This is asking for trouble ! Remove the assembly and give it a good cleaning and sanding of the friction surfaces to restore bite. Incorrect assembly can impare its proper function, and it MUST be able to clamp together quite noticably, the later double disc pattern is advisable. I always mark the knob to indicate when barely biting -- and mildly -- and when fully engaged for speeds above 65/75 mph. This to enable a glance to inform one that it is indeed tightened to the working mode. Jack up the front end to ascertain the effectiveness at selected positions of one's knob, the mark to be pointing dead ahead. Racing brake plates up front assist in wobble control because weight forwards of the steering head compounds the pendelum effect so overpowering the dampers ability to regain control of the flailing mass. For the same reason I usually pull-in and lower the headlamps position by relocating the lower headlight stays to bolts nearby on plate FF-32. Looks neater and more compact as well.
