Ninja 250 Captive Spacers
The thread below got me started on making a set of captive spacers for the rear wheel a while back.
http://www.ninjette.org/forums/showthread.php?t=153501 So I finally finished up 8 sets and have several people interested in purchasing a set or two and wanted to gauge interest in these and see if there was a market for them. Their made out of 6061 Aluminum and are 1/3 the weight of the stock ones. Same dimensions (within tolerances) as stock spacers just with extra flange to lock into dust seal. Video of the prototypes in action.

But without a 300 for me to test them on I couldn't sell them as 300 captive spacers. Ill gladly send someone a set to try.

I want! I'm also very interested in the front wheel version.
In the video, how do you keep the rear brake assembly from falling off it's alignment slot? |

Its 3D printed ABS I did brake that one so I might make some out of delrin eventually. It did help with putting the rear tire on. Secret is to spread the rear brake pads open. I'm going to make a bunch more this weekend. Will have a for sale ad posted this weekend.

Tested the front prototypes last night, with the speedo side being so long I'm not sure a captive spacer is going to work on that side. Still working on it though.
I can definitely make a standard spacer for a speedo replacement if people want. (Canceled)

Maybe just a captive spacer for one side and just leave the speedo be? It's one less thing to worry about. Plus, the speedo doesnt seem to want to come off so easily anyways.

and just FYI, the 300 doesn't have a speedo sensor. I run a 250 wheel on my 300, and have to use the speedo sensor to match the spacers.

One of the drawbacks to running a captive spacer is the amount of drag the dust seal has on the spacer itself. I installed my ceramic wheel bearings in my wheels and spun the wheels with the stock dust seals in place. The difference in drag didn't seem to be extremely noticeable. I then realized the dust seals were dragging on the spacers. I took a dremel and shaved them down a tiny bit to clear them from the spacers. Once it was all back together I spun the wheels again and they rotated for days.
Yes, it sucks that my spacers fall out easy if I'm changing tires but the upside is there is next to no resistance when the wheels are rolling. Every little bit helps when you have low horsepower and this helps get all of it to the ground without fighting the motor. But it's up to you guys. Do you all really need to change your wheels that often or quickly? I race too and I've never seen the need for it unless you're doing an endurance race. |

haha its another trick part. custom. @shane liberty
I think the rolling resistance of the spacers is .0000025 hp loss. I like the idea of 0 resistance but I also dont want dust in there....

The inside edge of the dust seal that touches the spacer. That's the surface that rubs the spacer when the wheel is spinning. I shaved it down so there's no contact. It means your spacers don't stay in but there's no resistance caused by the seal. Just a little trick I learned. Same thing as not over tightening your axles. Use the safety pin to your advantage. Over tightened axles cause drag. There's absolutely no reason to use an impact to tighten them down. |

I had Dave at worldwide bearings specifically tell me to run my seals or expect shorter life.
As far as these spacers go, if you cut the ID dead on and cut the OD undersize by .05 -.1 mm where the seal rides, leaving the inner ridge as is, then you would still get a good seal with less drag...best of both worlds. Hear me @DCMoney |

Totally understandable man. I totally understand. Also, I wasn't suggesting you remove the seals, I've only removed a tiny bit on the inside edge to reduce drag. The seals are still in place. Carry on gentlemen. Pay no attention to the peanut gallery (me) I'm just another looney tune from SoCal. |
