F3 rule change?

[Whitebait]

I've got a question with the new F3 rules.

1.1 Multi-cylinder four stroke up to 450cc
1.1a The working displacement of a 3 or 4 cylinder 4 stroke (Producing power hp) shall be no more
than 450cc.

Where does this leave the Ozzy 450??

It has a working displacement of 600cc..........does it not???

I'm looking at going down the 600/450 road next year!

No it has a working displacement of 450cc. One cylinder is not working.

Yup, like boostin said. The 4th cylinder sucks hp, it doesn't produce it.

[t3mp0r4ry nzr]

yeah bro, this sounds like a rule to clarify where the likes of the ozzy style supersport bike fits in. as boostin has said, the working displacement is 450cc as one cyclinder isnt filling. Spose this rule means there is no doubt as to its legality within the class.

it has a working displacement of 450cc. If she dont go bang then she dont make no grunt. the line producing power kinda sorts that out.

looking at that line the intent would be to stop over-boring (i.e. making a 454). it may have come about because the yanks have 450 superbike but you can have a overbore allowance (something like +.1mm overbore) giving a real displacement closer to 460cc.

[lostinflyz]

does anyone know if the ozzy450 is racing the club series???? or another 450/600.

[sinfull]

Has been seen floating round manfied this winter series !

[SWERVE]

Im really looking forward to seeing some of these 450 machines out there.:woohoo:
Will be watchin very close as this could be the next stepping stone for my lad.

I hear there will be one up and running in the SI shortly...

[Whitebait]

Thats all good!

I thought the working displacement was the total amount of cc in action inside the motor!

[k14]

Yes it is... so for the ozzy bike the total amount of cc in action inside the motor is 450cc.

[SWERVE]

Hey K14
How soon is shortly:whistle:

[nsrpaul]

I hear there will be one up and running in the SI shortly...

i hear`there will be two, shame ones not mine

[GSVR]

I hear someones doing the job properly and making a sleeved and stroked 450 four from a 600!

ive heard this has been coming each nationals for the past 3 years.

I'm Sorry Gary but as my bike currently holds 2 laps records and an NZ title unitl something else that is 600 based beats it I will claim I have done it Properly!!! And as for value for money it cant be beaten! Just wondering when you are going to actually do something yourself???
You always seem to have lots of ideas about how everyone else is wrong!
It is easy to talk the talk about time to walk the walk???:crazy:

NZ and its tall poppies!:argh: Go the Ozzy 450!

[roadracingoldfart]

Its a brave statement in saying "i have done it properly " with a certain concept when further options have yet to be tested with what may be better or similar results.
A sleeved 450 / 600 may be a good package but i wont say either is the best until both are tried on the track for a direct comparison.

there is no subliminal :bash: intent in this post

Sorry to have offended you Chris. But I have praised your bike and the concept many many times and consider it to be the best platform (bang for buck) for anyone getting into a competitive F3 bike.

As you well know the F3 rules have many twists and turns which allow for many strange combinations of frames and motors.

You can run a full on GP frame as long as it doesn't contain a competition road race motor ( A competition dirt bike motor is OK though).

You can run a 250 two stroke road motor as long as you don't fit any 250 GP parts to your bike.

Or am I just reading the rules wrong.

From a purists point of veiw having a redundant pistion going up and down does not make sense but the alternatives in this case cost mega bucks and many hours of work for a slight improvement right?

"Properly" option would be to get Yamaha to build a 450cc MGP bike and contract Rossi to ride it.

Maybe Chris is my new replacement for Robert as windup man!

And twofifty GP bikes can never be included in F3 as they are just too fast even the 20 year old ones!

Cant argue with two lap record type performance and you havent even developed it properly yet :angry2: , - or have you........:whistle:

I have been keeping GSVR busy over the winter - so dont try and coerce him back out on the track Chris , he hasnt got time.:pinch:

Great to here thatthere will be at least three bikes running on three out there this season and hopefully a few good twin lungers too........

Shame the one that lived here now lives in Italy

and Greece and USA and UK and Australia and Isle of Man.

yer thats me gsvr just got 98 hp out of it:-}

while we are on the topic of F3 rules.

is a KTM660 engine in a RGV frame legal? - do you have to retain the original ktm airbox?

are offroad based chassis still a no go or can you have a rmz450 with road suspension, clipons etc now.

Also why did MNZ lift the cc rating of a 400 multi to 450. introduce the sv650 and allow the ozzy450 while still capping 250cc production machines to 250cc. I guess its to get rid of all those 20yr old smokey old blue smokes?? You can buy 300cc kits for most now days. imagine that?

Yip the KTM single would be all OK Steve, & you could run whatever airbox you like. Dont see any issues with the MX/motard frame thing, just the handlebar height rule that some clubs apply.
Re the 250 thing - the rules go back a long long way, & in the day when there were a lot of 250 two strokes around , there was a lot of parts & development going into them. The general idea i understand was to keep puka 250GP technology out of the class.
I tend to agree though that a re-bored 2fiddy proddy based unit - would be a lot of fun and more in the hunt in our modern day.

Write a submission to the powers that be - & you never know your luck !

To true and the "supposed" new RD350 that Yamaha is looking(or just teasing) at releasing would be a mouth watering prospect in F3.
