This review is going to be short, as someone from Bricklink already posted a large one which is pretty accurate for me. Here, I'll try to point out the main reasons why i think this model is better than the 42130 BMW M1000 RR.

First, the kickstand. What I hated the most in the BMW is the lack of it. LEGO provided us with a rear swingarm stand and an exhibition stand, which are nice but you have to rely on them. On the Yamaha, the added the kickstand. It is crude, but does its job. They also provide you with an exhibition stand, and it also is better than in the BMW, taking the bike off it is much easier.

Second, the gearbox. The implementation of new parts pretty much revolutionised the gear shifting mechanism, and I'm sure this will be used in many Technic sets. Other thing is, the shifting itself isn't as fluent as it should be. And too bad there isn't much to observe as the gearbox is covered by the fairings. But oh well, you don't see the gears shifting in the real thing, do you?

Third, the playability. I've graded the BMW's playability to 4. Now I think it deserves to 3 at most. The falling System parts were the nightmare and forced you to proceed with extreme caution when taking the BMW off his stand. The Yamaha is much more sturdy and durable. You can feel its structure is more compact and damage resistant.

What I don't like in the Yamaha is that not every part is like in the model bike. Take the mirrors for example. Totally different. And it's price. With almost 500 less bricks than in the BMW, it's almost as much expensive and that wasn't nice.

All in all, this is a great set, with a revolutionary gearbox. Despite its price, still worth the money. Glad I bought it. Looking forward to more similar bikes.
