I now own the bike so I can go into detail about the differences
The Lockwood bike always goes at full speed, instead of a toggle like Konami's
There is no flaming jet despite Lockwood's artwork
Lockwood's has exhaust plumes coming out of the exhaust pipe for the rider, Konami's doesn't.
The front mirror is transparent with Lockwood's
When at a stanstill, you rest one of your hands on the accelerator with Lockwood's. Konami's plants both on the rest piece.
When riding Lockwood's, the rims spin quickly but the actual tires rotate slowly
Lockwood's is much bulkier than Konami's making it larger.
I'll post pictures to compare later.
