Just my opinion but for the slight increase in power going up a few years to a newer motor, between the work and cost involved your better off just getting a new 2016 model.

 

I'm talking about if you have $10-$20K in aftermarket parts that won't fit the new bike. Like BST wheels, Braketech rotors, carbon fiber fairings, magnesium frame parts etc. In that case it would be desirable to keep the older bike with the custom bits I think.

 

I have seen where some have swapped a '07-08 engine into an '04-06... but not a lot of gains & prolly not worth the effort... other than that the fabrication & expense required would be greater than selling the bike & purchasing a newer bike

 

I've seen that one too, he was on this forum. The 07-08 R1 had variable v-stack heights which was really cool, but besides that it was really similar to the 04-06. I think the fairings are an easy swap too, almost the same bike.

What would it take for example to fit a 2016 ZX10R/BMWS1000RR/R1 into a 2004-2010 R1/GSXR/CBR/ZX10 ? Are the sizes that far off on a relatively modern bike? I know the mounting points would be different.

 

It'd be next to near impossible to try and shoehorn any engine into a different frame... especially across brands

The engine on most modern superbikes is part of the structural integrity of the frame, and the frame is going to be made to fit the engine, so the dimensions of the engine would be more of a concern than mounting points, IMO.

Could it be done? Sure, just about anything *CAN* be done, but that $20k of parts you don't want to replace would probably be a drop in the hat compared to the fab and R&D costs to modify a frame to take a different engine (properly/professionally, some moron could probably make it *FIT* much cheaper)

My 2 cents.

 

Cool, I was just curious. I see a lot of bikes at the track with ridiculous amounts of money invested in them and I always wondered about this.

 

The only things worth spending good money on for a track day bike are suspension and maybe brakes.
My opinion.

Race bikes are another thing.

 

but suspension isn't made of carbon fiber and doesn't have neon lights on it!! :grin2:

 

the great thing about riding bikes is that we can experience the power and handling of the best supercars. for pennies on the dollar. im satisfied for the most part with what yamaha gives me. i dont see a reason in spending time and money on a swap that produces very little over a very well engineered product.
