Frame help

[goshine201]

Hey guys, so recently i have started looking for powerful engines hoping to build an awesome mini bike. While searching i found a beast 1985 v65 sabre engine. The thing is 120 HP with 9500 rpms and shaft drive. Im hoping to build a frame from scratch but im kinda scared of it breaking at such speed. Could anyone suggest a nice and STABLE frame design? or give me some tips on strengthening the frame? The frame can be full sized, im not hoping to able to build a 120HP mini bike.

Thanks in advance.

Welcome to the forum

For an engine that size, I wouldn't use any frame that hasn't been manufactured by professionals who know what they are doing. Unless you have got extremely good fabrication skills to build a frame that will withstand all those forces that your engine is going to put out, I wouldn't do it.

I hate to be a killjoy, but we don't want to see people hurt

Thanks for letting me know. Im kinda bummed out, but its better than having the frame collapse traveling at a 100 miles an hour. The reason i thought this was possible was looking at the actual sabre frame all the metal seems kinda thin and the welds are possible to replicate. Would anyone know of i decent, cheap frame that i could purchase?

Thanks for the advice.

I would do a search on Craigslist. Whatever you get, you will have to brace the shirt out of it to handle your engine though

I'm not hear to bum you out or anything, but with all that horsepower, you will pick the front-end up eery time you try to hit the throttle unless you make it pretty long with a lot of weight on the front. I had just a small 5.5HP Tecumseh on a Baja frame and when I took off, The front lifted up and I found that biting a steel pole for a basketball hoop hurts like hell. I was geared more for speed also, I was running a 5:1 ratio. You might want to run at like a 3.5:1, but even with that, it might be too much.

lol... I'd love to see this thing built, but I'd never actually ride the thing. I agree with the other posters, self fab'ing a "mini" bike frame for a 100hp engine is bonkers. I have a mini chopper with a 6hp and I can lift the front wheel off the ground, and I'm 220lbs. Post some pics though, that always gets more peoples attention.

Im not really hoping for a mini bike with 120hp but a homemade chopper or motorcycle would be awesome. This thing is from a 1985 sabre, once the fastest motorcycles in the world, so it's go lots of speed. I'm thinking I'll just buy the sabre frame used from ebay. The interesting thing with this engine is that it's shaft drive.

But honestly who wouldn't want a 175 miles per hour baja

i have to agree with landuse ......but if you do build it make sure you put a few band Aids
in your pocket before you ride it just to be safe
