Thank you. frames are everything. the most interesting part of these copart builds is that no one wants to check or talk about them.

this channel is way underrated. Thanks for the info

Thanks for your encouragement Jorge ✌️

Thanks man! Great video. I mean it's nothing too difficult, but it's nice of you to make this so understandable and simple and clean. Thanks. Now I will check the straightness of my crashed tdm 900. Hopefully it's not too out of shape. Thanks and cheers!

Good job Tristan and thank you for your time and effort to make this video. I wanted to check the frame of my bike after an accident and I Laser inspected the frame against the factory figures. There is a lot more to it than the vertical orientation of the steering stem. Verticality on mine was fine but it failed on rake (-2.8cm) and an upward height displacement of the bottom of the stem for about 0.9cm caused by a head on strike. My bike now has a noticeable transfer of weight and an inclination towards the front exceeding the factory settings and changing the handling too.

I understand what you’re saying, but I’m trying to do things safely without spending hundreds and wait months for the frame control guy to be available I tried to get the factory specs on the frame: I wasn’t successful So I didn’t know how to measure the rake My technique is not bullet proof but would honestly weed out a bunch of frames, of course there is always the frame that distorted in a very symmetrical fashion, I just don’t think it’s frequent

@@TristanDurandBuilds Don't get me wrong, I understand you have made an honest effort. All I am saying is that it may not be the most appropriate method for bikes like the R1, Aprilias, MV's and such bikes that people use often in track days and racing circuits. Maybe good for a less demanding rider or bike but when you have a bike that corners at high speed maybe too much of a risk to not test the frame properly. Thank you for your reply.

Great video, very helpful thanks for sharing

Thanks man !

Thx, that was helpful. But i think you should have measured front rake too. For example i had front hit in accident and rake may have changed i bit. I would use your method to measure frame geometry for sure, but it needs to take frame apart, not sure i want to do that))))

I simply don’t have the information that tells me how to measure the rake, believe me I tried. So the rake on an R1 is 24° on assembled bike with the reference being the vertical. But how do I position my frame alone to have that reference? I just don’t know how to create a reference that I can measure against…

Fantastic video on how to measure and determine if your frame is straight, but the title is very misleading. There is no control you are measuring against, as though there was an experiment, and you are not exerting force to change (control) anything. With a more accurate title you may get more views. Other than that this is great information.

Thanks for you POV ✌️ I would say that I’m definitely controlling the frame, what I am not doing is measuring distances or the caster angle as I don’t have the Yamaha shop documentation that tells me how to reference that caster angle to.
