As you can probably understand, I believe the oval pistons caused all sorts of interesting issues with regards to thermal expansion, etc.

Honda NR - Wikipedia, the free encyclopedia
Was cylinder count...
Not bad for a 500cc *4 stroke* ...
btw... the NR oval pistons have little to do with the VFR... not sure why they were posted up, but...  |
It was essentially an attempt at a "pseudo V8"
