- In Ep. 2 of our parts series, Richard talks through our forks and front suspension. Our network of craftsmen manufactures everything on a Janus 250 fork besides the shock absorbers, which we leave to the experts at Ikon Suspension. Subscribe for more videos!

Thanks for explaining this, now I want one of these even more
A family friend raced an AJS that had a similar fork set-up back in the sixties. I remember him putting a clutch lever all the way through the the top of a boot through his foot and out through the sole on that bike. Now we have balls 🤣 on the end of those levers, Lol! Rest in peace Bob Hall!
Nice explanation of the Earles fork design. I appreciate the anti-dive characteristics (really appreciate this aspect of my BMW's telelever front end) as well as the fact that it allows you to make most front end components close to home. Simple, effective, and distinctive.
You guys are doing some original thinking and design. Evident from the choice of leading link forks. You are not just blindly following the general trend of using telescopic forks.
Very simple and high-level description of the system along with the historic references. Quite enjoyable video. You guys know what you are doing. Keep up the good work. Godspeed ahead.
I love the look of your forks.
I love this series of videos
Will look forward to all videos, On how things work and are designs for your bikes, Hope i will be able to
buy one in UK one day Keep up the good work
Well done Guys - is it possible to purchase a set of these forks?
It's kinda like a swing arm in front. Cool
Agree on the antidive theory, but there is another aspect of the steering geometry, which is the linkage will make the front wheel offset vary in action. For example when you hit a bump, the spring compressed, wheel axle move up in comparison to the pivot point of the linkage, it will increase the front wheel offset, therefore reduce the trail, make the bike handle unpredictable. Correct me if I'm wrong.
Peugeot Speedfight gen 1&2, mopeds had a similar arrangement to this but single sided.
I deduce these bikes are built like tanks. The design looks like one less thing to break, you replace the two shocks when they get old and I'd guess you could do it yourself if you don't live near Goshen.
What's the Ride Quality in this Suspension Stiff or Comfortable? And if Stiff then do you have more comfortable options in this.
Very interesting! The steering angle you arrived at seems to be rather steep, nearing 70 degrees. That actually rings true with me since the offset mass placed behind the wheel axle should provide extra stability. Would you be prepared to give me an exact figure?
Are the shocks rebuildable and if so, would they be returned to your shop for rebuilding or is replacement the most economical route?
Hello! They are rebuildable. You can learn a bit more about them in our parts episode on shocks: ruclips.net/video/_d-nueRcURo/видео.html

Like your design but modern inverted telescopic adjustable fork designs and builders would school you differently in your assumptions of how they work and function on the track and the road. There are far superior forks than these but to keep your build as in-house and cost efficient as possible I thoroughly understand why you went the way you did. To simply dismiss modern forks as inefficient is a disservice to the industry and a bit arrogant when comparing your two rear shocks to what is out there today
I think that your stance is very arrogant in return. All the arguments used here are more then valid. Assuming everything should stay as fashion dictates it is often only proof of inherent conservatism.
Agree about keeping things in house. Otherwise you're just American Chopper, putting parts together!
