What's up, people?
I was wondering if any of you that are into dirtbikes could help me out a little. I currently have a 1982 Yamaha IT 465 enduro bike and was thinking of trying to locate a newer YZ 450 aluminum frame to transplant. I know anything is possible with money, but thought I should maybe get some feedback before I delve into this endeavor.
As far as I know the engines between the two are close in size. I don't know any one that has a new YZ 450 for me to measure the engine but they look close. Slight modification to the frame (for mounting tabs and whatnot) is acceptable. I just don't want to be cutting up the whole frame, cuz then what's the point.
I realize it would be much easier to just forget about the IT 465 and get the newer YZ 450 for riding. However, Ive grown quite attached to the power band on the IT 465, and let's face it, it's one of the meanest bikes ever built. It is a 465cc 2-stroke. It's just that it's become a rough ride and suspension components for it are scarce. That and it was built as an enduro bike and so it does have an old, heavy steel frame that is a little long and hard to turn. Also, it never had good landing characteristics, even when the suspension was new. That's how I came across the idea of transplanting to a YZ 450 aluminum frame. It would give me up-to-date, upgraded suspension options and a much more manageable bike for the hard riding I do.
Any and all input would be greatly appreciated. Thank you!

I don't know anything about dirtbikes other than they are basically off-road motorcycles and the fact that I want one

do you know if it has to be that frame for your bike? is there anything else that might fit better with slight modification? if so, I could ask my dad about it, he just got a DR 650, and I could ask for his opinion on your situation.

It doesn't have to be that bike. I was just looking to put it in the aluminum frame that the yz450 has.
