Tier Motorsports WR 250 proto

Fresh out of the shop. A few minor tweaks needed prior to sending the parts to get painted.


The basics seem to be working as planned. Some more dialing in on the suspension unit and we'll be off and running.


Front fender art work

Here is the front fender and decals design from our favorite industrial designer, Adrian Sellers. The goal is to give the bike a more modern look to better match with the front sing-arms. The Tier Motorsports logo in blue is also an interesting touch.
Feedback is welcome.

Now with Headlight and rear mud-guard

It is starting to look like a real bike!
We're still missing the gas tank and right exhaust plastic but we'll worry about those later.
Proto parts are due in a couple of weeks. Can't wait to ride the beast...



3D scan of missing fairings pieces

While the front swing-arm parts are being fabricated we took our NextEngine 3D scanner out of its box once more to scan the missing fairing pieces that will complete the bike assembly in 3D. This will allow our industrial designer, Adrian Sellers, to generate a front fender design that blends in better with the existing plastics. This data will also allow more photo realistic renderings of the complete unit.

Design Feedback

We just received feedback from our master industrial designer Adrian Sellers. His quick review shown here highlight what curves blend into the existing bike geometry. New graphics on the plastics will help in that effort. There is also a need to work on the tubes between the
triple clamps to move away from that "fork look". The front fender seems like it is going to go through a face lift as well.

Animal Motorsports

As we were translating (via Google) a German blog that was discussing our Tier Motorsports models we've found out that "tier" in German means "animal".
We kept on seeing "Animal Motorsports" throughout the translated document. It is interesting as it match well with our "feline nose" logo.


Swing-arm curves

The last shot (top view) show how the swing-arm curves blend in to the rest of the bike. Very cool if you ask me...
And yes we'll eventually add the bulk of the missing parts to make it look like a real bike. We just have other priorities right now and this was just a quick confirmation exercise.




Quick rendering for fun

The beauty of doing all this on the computer is that color variance are just a click away. Do I hear KTM anyone? No, we're still focused on the Yamaha for our first models but it is interesting to see what it would look like in orange...

63 Degree Lean Angle

A common fear in using front swing-arms is the reduction in lean angle, since the swing-arm has to be widen to clear the wheel during steering. This is easily "solved" by raising the swing-arms upward where the wheel movement is the widest during steering. The photo below show the approximate 63 degree of lean angle our current prototype allow.

Brake and Steering Bracket Done

The view below show the best location we have found for the brake caliper from a clearance to the swingarm point of view. This also allow us to use one bracket to hold the caliper as well as the steering linkage.
