Not that an 1100 or 1300 engine is that much heavier but add that to the torque that a bigger engine will put out I don't think the frame and suspension are anywhere near strong enough on the 650's. Also, you would need to measure all the mounting areas for fit and customize/fabricate anything that didn't pan out. Also, as you customize the bike you also make resale value limited to someone looking for exactly what you've done. Short answer- Why bother?

Since you have not bothered to identify the bike you have or the donor models it is impossible to answer. It is probably possible if you throw enough money at it. Have you thought about tuning the 650 or adding a turbo and/or nitrous?

SI, meant you can't put 10Lbs of sh*t in a 5lb box. Think of all the FUN you'll have customizing the 1300.

It's always possible if you have time and money. The biggest problems are the frame and the engine size. Any 1300 engine weights a lot more than your 650 lump and it's a lot larger physically. Your 650 frame wasn't built for the extra HP, size or weight of and 1100 or 1300 engine, so you will have to beef up the frame. Your problems move out from there. You have to move the engine management system over, then the final drive, then the suspension, etc. I think you know where I'm going here. Yes, it's possible. Yes it can be done, but sometimes, it's better to buy the larger bike and start the farkeling over again.

please don't even try to do this. the 650 frame will not accept a larger motor and it is not designed to accept the enormous increase of power ffrom a larger motor. IF it even could be fitted, your life would be in danger as frame breakage would inevitably happen and no amount of riding skill will get you out of THAT incident. Stay alive, keep your beloved 650 intact and in the lounge as a showpiece and go buy the bigger bike that you want
