I'm heading to the dunes with my son for his first time next week. He'll be riding an RM85. It currently has the standard wheel size mounted but I have the big wheel kit also. I'm thinking the big wheels would do much better in the dunes. He's not super aggressive and being this is his first time anything to make it more like dirt will be better.

I have a couple 85's and I could swap the 14" between the 2 bikes since only one has a 16" wheel. So do I go 14" or 16"? Anyone have experience between the 2?

No experience between the two but the dunes will require as much power as possible. The larger wheel might be too much for that bike to pull in the sand. (Geared appropriately you would be fine.)

I had the 150r small wheel back when it came out and I ended up getting a big wheel set as I got bigger and my dad always put the paddle on the small wheel. I believe they have the same size wheels since it was the same class (correct me if i'm wrong.)

Thanks guys. I'm gonna go with the 14". That'll keep a little more load off the engine. Should be fun.

Go with the bigger wheels and just drop a tooth on the front sprocket (that's what Suzuki does on the RM85L). That will offset the larger diameter wheel and the load will be the same.
The larger diameter wheels will stay on top of the sand much better than the small ones will, making the experience better.

Order a new top end for it now. Bring a clutch with you as well.

My friend got this shot of me with his DSLR. The old YZ426 still has it.

A 85 with a paddle in the dunes isn’t gonna be happy.. can it be done sure but depending on how good your lil dude is it’s gonna be a long day.. if he is slow the front end is gonna be in the sand and he will be all squirrly. If he is fast and on top of the sand the bikes clutch and piston are gonna be angry...
