I added the nose fork from Zenith for the 21 inch tire.

I used a 700X600 tire. The 21 inch will rub, lack of clearance.

Overall, I'm pleased, gained 2" prop clearance!

I'm running 600x6 6 ply Airhawks on my 701. Are you using tubes? I did for a while then went tubeless. Got rid of a buncha weight and I can plug a hole in the field. Or just go home on a flat.

Tubeless all the way! Works well for all the reasons you stated.

Don't have to air them up any more than tube type.

I also changed to a 3/4" hub and 3/4" axle with castle nuts. ( thru axle)

Looks great,

I am confused though.  You said you order the 21" fork, but then stated the 21" Rubbed?

But glad it worked out, seems like it would be better all the way around?


Yes, it was stated, and in the part# for the 21 inch tire.

The 21" tire size is  21x8.00-6, the inside radius of the fork is 8", while it goes over the tire it's going to rub

I already had the 7.00-6, so it worked. I assume Zenith made the fork to fit the curved strut and that's why

it's not wider. I might try a 21" tire at a later date.....$$$

To clarify, the fork is tall enough for the 21" tire, just needs to be wider in my opinion.
