I've been riding 37 years but I am new to Triumphs.
I'm interested in buying a brand new or almost brand new Tiger Rally 900. I am interested in this particular bike because of its light weight as I plan to hang it on the back of my motorhome.
What is the difference between the 900 and 1200 engines? Can a 900 be punched out bigger? Why does the 1200 Rally weigh so much more than the 900 Rally? The shaft drive cant be that heavy.
Thanks for any info.

You want to increase the engine capacity even before riding the bike ? Maybe it's the wrong bike for you ? Maybe you should look at the new Multistrada V4.

Actually, yes. I guess it comes down to... I want a 1200 engine in a Rally 900 package.
I just figured there would be stroker or big bore kits available but I'm not finding any info on the subject. I did look at a Multistrada but it's too heavy for what I'm trying to do and I also plan to do some trail riding. I also don't care for Ducati's valve setup.

Very rare to find big bore/stroker kits for new modern bikes. Too expensive and with modern machining tolerances are already quite tight not leaving much room to update or mod a motor.

I notice that the 900 has a 3.07" bore and a 2.437" stroke where the 1200 has a bigger 3.54" bore but a shorter 2.38" stroke.
I wonder if the 900 cylinders could be bored out and a 1200 rotating assembly could be installed with headwork or even a 1200 head?
It would be way easier to just buy a 1200 Rally but I don't want the extra 117 pounds of curb weight. The 1200 is 549lbs vs the 900 at 432lbs.

And yes a good part of the added weight is the drive shaft, they're heavy.

It looks like the most apt response so far is on the bottom line of @OKTriumph's sig.

I've seen some thought bubbles on this forum but this ones a doozy.

How can someone judge the T900 power to weight ratio without even have tried it?
Unless being a Pro rider, I doubt it wouldn’t have enough power/nimbleness to satisfy most riders and that you can ride it at 9/10th+
My 2 cents

Couple of self fabricated aluminum brackets, some spacers, a welder and I bet you can wedge a 1200 motor into that 900 frame....

Something is not correct with your figures

Weight measured by Motorrad both with full Tank
Tiger 900 GT Pro 227 kg = 500 lbs
Tiger 1200 GT Pro 251 kg = 553 lbs
Difference 24 kg = 53 lbs

I estimate for the Rally - Pro the difference ist about the same.

You are correct!
I went back and rechecked Triumph's 2022 model website. The 900 spec lists dry weight and the 1200 spec lists wet weight. I didn't catch that before and now I am wondering what the "dry" weight of the 1200 Rally might be.
Thanks!
