With a moto wheel and moto tire, What are the different options or combinations in terms of diameter, width, ...etc. to achieve about 24 inch total??? I know nothing about moto rims.
I was really suprised by the 9.5kv rating, I expected 13-14kv based on the italian guy's posted 84mph. I just talked with JRH, and bumped my rim on this build up from 17" (@22" OD) to 19" (24" OD), which only gives me about 8% more speed. The actual diameter of the wheel depends on the height, which depends on the Aspect and Series for that tire, but 24" is a good rough estimate. I hope my last-minute change doesn't delay my build too much, JRH has been really good about it.
I'm probably going to start with my Methods controller before moving up to the Kelly, here is the workup I used to compare 17"/19" performance at 100v:
24" 22" Diameter
75.36 69.08 Circumferance, inches
6.28 5.76 Circumferance, feet
840.76 917.20 revolutions/mile
9.50 9.50 KV of CroMotor
100.00 100.00 Voltage
950.00 950.00 RPM Unloaded
67.80 62.15 MPH unloaded
760.00 760.00 RPM Loaded (80%)
54.24 49.72 MPH loaded
John sent me a link with some 19" tires
http://www.treatland.tv/SearchResults.asp?Search=19+tire and I went with the DeeStone 2.5". Once I have the build stabilized, and I can examine the tires first hand, I may go up to a bigger diameter - I have about 3.5" where I expect the sidewalls to land, too bad the aspect is not the widest part of the tire. OTOH, a lot of these tires are HEAVY. I had a poke about on Amazon looking at 19" tires, below is what I came up with, sorted by Aspect then series. When I moved onto Motorcycle Superstore, I didn't find any new options. I like the bridgestone spitfire and TW39 a lot...
