I find it hard to find any fault in plain jane old Maxxis Razr tires... front and rear.

They are great and great for the price thanks to the Razr2.

They get good traction, wear a long time and are tough.

And even if you prefer the ITP holeshot grip on hard surfaces, you can still grove them like holeshots... and up front I think you'll prefer their more solid center tread in the sandy soil. And you can also groove the front knobs for hard pack bite, and grove between the knobs to make them more like the Razr2 or GNCC.

I put GNCC's on my Kawi though... but the jury is still out on how I like them overall.
If you go that route, go with the 22" front and 21" rear though.

I have the 22" fronts and 20" rears... and the rears are only just 20" tall full of air with full tread... and the part I did not realize is they are only 10" wide. From a distance it looks like you just have stock tires.

Clearance and flotation will be better with the 21" and you'll have more choice on air pressure.
