We have several Kits Available to Modify and Upgrade the Razor Dune Buggy.
Looking for easier option to trade torque for speed I've looked at getting larger tires. Axle seems to be 20mm which is just a hair larger than 3/4". I've order a 3/4 go kart hub to see if it will go on with persuasion. If that works I can bump up these 7.5" tires to 9, 10 or 12" tires easily. 12" would give me about 60% more speed. Too bad nobody sells a wheel with 20mm hub
I've received the hub and am waiting on delivery of a 51/64" drill bit. Meantime I've found a great deal on 14.5" wheels. Only issue is they have 1" hub bore and we need 20mm for the Dune Buggy axle. I found a sleeve that will fill the gap but can only find it in the UK and though it is only $5 they want $35 shipping for one and an extra $14 for each additional for a total of $59 for just two. Here is a link to what I'm looking for though it is 25mm outside diameter and I'd prefer 25.4mm to match one inch. Please let me know if any one can find similar for less. 1" (or 25.4mm) OD, 20mm ID and 85mm long would be ideal but I can use several to come up with 85mm if you find something shorter and could cut one down to 85mm if you find longer.
Awesome, super helpful. I've placed an order for 4 of these that you've mentioned. Should work great. I plan to cut a 5mm strip out full length or at least 3/4 length for the keyway so if it's a little tight around the 20mm axle then it will be able to expand somewhat. Wheels are also on the way.
With this adapter ANY rim with a 1" hub will work so long as it's not too wide. I may send back the 3/4" hub I bought and the 51/64" drill bit I've not yet received.
