I think that would be an excellent engine/chassis combo.

I've outbraked many bigger bikes, but I guess it will always depend on skill level.

400's have the same front tyre width (grip level) and are about the same weight (less in the case of our racebikes which to be legal have to be >150kg's), so I guess in the end it's up to rider skill.

The only bikes I find impossible to outbrake on track are GP 125's and those pesky motards.

This is getting way off track!

Can that huge engine fit in the little RVF?

good question

that doesnt look much different in size, the thing id be concerened about is that other engine being a different weight and the mounting brackets being i n different places so it may causing the bike to be unbalanced, and also the sprockets be out of line

not sure i like the way this site's been updated man! half my posts arent going onto the forum so ill try this again: the mods on my nc30 are:bigger fuel jets, fireblade brakes, front and rear braided s/s hoses, rear hugger, 750 rear wheel conv, aprilia 250 rear shock, ethos half race system...........

How about this one, it looks very close:

lol, see what i mean guys, theres alot of peoplke on here sayin, what about this engine or that one and this should fit. anybody actually got a working successfull example on here?

People are suggesting lots of engines as this isn't something that is done very often, since it's quite possible to fit several different motors, all with different characteristics, it will be down to the builder to pick what they like the most. i.e v2, v4, straight etc.

As for 'working examples' There was an NC30 with a VFR750 engine in it that was owned by somebody on here I believe. I've also seen a ZXR400 with an 893 fireblade engine installed in it.

Not noticed any problems with the forum today, maybe its your pc?

seems to be ok now thanks. a zxr400 with a fireblade engine! that would be worth a look see...........
