897 pieces, one satisfied builder

One of our members sent three photos after finishing the MT-07 and this build deserves the full look. The Yamaha MT-07 (42139) is a licensed replica at around 1:5 scale, and it packs in more function than the piece count suggests.

The parallel-twin engine is clearly visible once the body panels are on. You can see both cylinders and, when you turn the rear wheel by hand, the crankshaft movement is right there in front of you. It is not hidden under a cover. That engine detail is one of the things that makes the licensed moto kits worth building.

Working steering, rear suspension, and a kickstand are all present. At 897 pieces it is one of the shorter afternoon builds in the library, but it does not feel cut down.

Scale ~1:5 licensed replica
Engine detail Parallel-twin, moving pistons
Function Steering, rear suspension, kickstand
Livery Matte grey, MT series
Good to know

If you have not done a licensed moto kit before, the MT-07 is a good place to start. It is a bit lighter than the MT-10 SP (1,478 pieces) and builds in a realistic session. The engine assembly is the highlight and you spend proper time on it mid-build.

Also in the library

This is exactly why I like putting member builds on the blog. The official images tell you what a kit is supposed to look like. Member photos show what it feels like once someone has actually sat down, opened the bags, and worked through it.

If you have just finished Yamaha MT-07, send over a few photos. It does not need to be a full studio setup. A clean table, a finished build, and a few notes on what stood out are enough.
