ALL our Production  series reverse trikes will have a complete 17 digit VIN (vehicle identification number) and not an 8 or 14 digit "Specialty Construction" DMV or state issued number.  Unlike vehicles with 8 to 14 digit State Issued numbers owners of our vehicles will have no problems financing, insuring, transferring ownership or driving across the US border which will add to the market value of eMa Motorworks produced reverse trikes.  This full VIN means you can now Finance your brand new Hammerhead SR instead of having to pay in full before taking delivery
