I wonder what kind of frame the R3 is going to make use of. Right now Yamaha does have the YZF-R15/R125 puttering around emerging markets with a delta box frame. Its possible both R3 and R25 use the deltabox lifted from the R15/R125, but when the R25 launched Yamaha did say that R25 had its own all new tubular perimeter frame. Which is essentially what delta box is, but all new...

Although will the bigger engines fit in a frame designed for a 125cc?



any one know anything concrete?

Ok new piece of info, R25 and R3 will NOT be using the R15's frame.

The upcoming R25 is built on a new frame that features tubular elements instead of the R15-like steel spars.

Good info. How do you think Yamaha will improve on frames over the coming years with other bikes?

That would make sense since the R25 uses the R15 frame

So i'd imagine the R3 should use a larger frame.
no, no. R3 and R25 will share a new steel tubular while R125/R15 will continue to share the steel spar frame.

But does it say anything about the R3?

We are trying to figure out if the R3 uses the same frame as the R25.
Its logical bud. Yamaha is not going to design a new frame from the ground up for an increase of 50cc's. Just look at the Ninja 300/250 and the CBR300/250. Both use a larger stroke to go from 250 to 300 while utilizing the same frame and suspension bits...

But the R25 already uses the R125 frame

So the R3 if its 300cc will be built on a 125cc frame.

Not that its impossible. I'm just saying there could be a chance the frame was beefed up a bit for the R3.

300cc is more than double the displacement of the 125cc.

It would be a big waste, wasting millions for 50cc more :D
Only make sense to use the same frame and expand on it.
