Well they aren't called Masked Riders because they walk around with masks...
I went out and bought some Maisto 1/12 diecast motorcycles, I absolute love these type of bikes because not only are they 1:12 scale so they can fit either Figma or SHF figures, but they are also incredibly detailed and make beautiful display pieces. Decided to take a photoshoot of my Riders riding.
The bikes are cheap too, about $12 dollars on average, and they are widely available over the internet.
This is a BMW GS 1200, by far my favorite one I own, it's a simple black and white color but it looks gorgeous and it really retains all of the detail of the source material. I think this is from a later line so it's easier to assemble than some of the other Maisto bikes.
While I love the body mold on these two as well as the color and detail, my biggest problem with Maisto's bullet bike line is that the kick stand wears down after a while, and so with the added weight of the rider, the bike can easily push foward on the kick stand causing it to retract and next thing I know I got an out of control bike bowling over my figmas.
This is actually from New Rail rather than Maisto, but just as well detailed and just as heavy, biggest problem is it comes with no brakes to keep it from rolling forward so I always have to put it in a corner so it doesn't run over anything.
I absolutely love motorcycles and I love collecting little representations of those bikes that I like, they always make it more fun for your other figures too.
There are several kits that I'd love to buy like this one.
