Replacement back rim and spokes for my 2007 Honda CRF450x Dirt bike. And recommendations?

Every time I drive 20 feet the spokes get loose and my back wheel gets wobbly. I need a new rim ad spokes looking for good sites… Would prefer to buy the rim and spoke all together and not have to pay someone to respoke it.

I've done bicycle wheels, confusing at first & tending t obe long & rather boring but very satisfying when done. As Chris wrote take pics before you start & check UTube for info.

Why not respoke the one you have and save money.
