Since its hard to imagine owning a dirt bike forever, it is best to get it titled. Then you can trade it to a dealer if you want or you can sell it privately and the buyer will know there is not a lean on it.

True, you will run into a lot of folks that say that the MSO is as good as a title, however they are usually the ones that bought a bike without one or are the original owners who never titled the out of state bike so they don't have to pay sales tax.

The law in Texas is that whether or not you buy the bike out of state it is to be titled in Texas. You only pay sales tax when you purchase a new or used bike from a dealer.

<VERY IMPORTANT NOTE>
YOU DO NOT! PAY SALES TAX WHEN YOU PURCHASE A USED DIRT BIKE FROM A PRIVATE PARTY IN TEXAS. YOU ONLY PAY A $33 TRANSFER OF TITLE FEE.
