Break down of the R25/R3's Diamond frame construction...

 

[Yamahahaha]

This is a great diagram and all but considering a lot of it is in some other language, it doesn't give us much in the way of information. Can anyone give a bit more insight into exactly what we are looking at here?

 

[YR3]

unless someone is able to translate it, then we can indeed get some valueable information out of it

 

[Yamahahaha]

Weird how the main words in the diagram are in English but everything else is in a different language.

Here is what we can get from this:

- rubber mounts
- 2 coat painting
- sporty handling
- optimum rigidity balance

Anybody that can expand on those points?

2 coat painting is pretty much obvious. Sporty handling is probably more the seating position such as supersport. While rubber mounts on both the frame could mean that it will have a lower seat rail, runs a little smoother, is a bit heavier but more power which should off balance the weight. While optimum rigdity is probably pointing to the steel frame which offers an ideal rigidity balance in the longitudinal, lateral, and torsional directions, using the engine as a stressed member.

I guess most of that is stuff that we could pretty much infer anyway.

Are there any bikes that use materials other than steel for the frame? I just figure that there are lighter materials that they could use.

Yea but they're high dollar. Some of the Supersports will use an aluminium twin spar frame which is what all the GP bikes make use of (except KTM and their Trellis)

Pretty cool how it's what all the GP bikes make use of.

no its not what the GP bikes use. They use aluminium twin spars, as do most high power supersports, but the R3 is a steal delta box basically... its just more cost efficient. ..

Good to know.
