748R Frame and Testastretta motor ?
 

Hi I read this somewhere about a 748R frame:


I thought that the testastretta has 12mm framebolts instead of "old" 10 mm.

So does the 998 engine fit without modification to the frame?

Skidlids is the hybrid expert...ping him a U2U

I've just had a 996S engine put in my 916 by Moto Rapido, they sleeved the 12mm mounting holes in the engine and used the 10mm bolts.

As Jools mentioned I have my Hybrid which is a 748RS frame fitted with a 998Bp engine, both the frame and engine use 12mm engine bolts as standard.
I can check my 748R engine sometime to see if that has 12mm engine mounts.
You need a bit more than just the engine though, I also fitted the twin fan rad, oil cooler and pipes, harness, Airbox and repositioned the coils.
