Just a hypothetical question. Supposing some body could fit a 12R motor into a 7R. 1 what is the weight difference between the two power plants. Any one know how much these motors weigh?

how do you suppose the handling characteristics would change? is there more weight at the top or at the bottom? This would not be a drag race bike but a track day bike (road).

Yes I know it would be a wheelie monster.

Could one stick with a 180 tier?

what is the deference between a 7RR frame and the 7R frame.

thanks.

Spotted frog,
I looked at that proposition when I shoehorned a 900R engine into a 94 ZXR750. The 12R motor is too wide and tall, it would also take serious frame surgery to get it in and the 900 engine was the best way to go.
Question 2 the main difference is the adjustable swing arm pivot and not much else.
