I've never seen any decals for sale for the engines and I'm sure if someone had them, I would have run across them by now. I have seen plenty of V-RROOM! motors without them, though and it would be cool to be able to restore these motors with new decals!
My Stallion is also missing the decals as are most of the bikes that I have seen out there online.
The V-RROOM! Bronco Bikes had decals too. Not sure what the production numbers are on these bikes, but how cool would it be to offer the V-RROOM! bike decals and maybe even the "Police" version decals so you could build your own "Police" bike!
Can you advise if you had any success with the creating of decals for the Mattel V-rroom motor? I recently purchased one that is missing the dial sticker, I attached a photo of what it should look like. Please send me a response to my email email@example.com.
