The 50

Honda NF4 bare frame
I have decided I am not going to use my NF4 frame as I'm too old for it to make much difference. So I have a bare NF4 frame for sale, PM me if you are interested.
It's cheaper than this one

Who let that 250 in?

Mr. Steer and I took a cutting tool and grinder to my Aprilia chassis and surgically removed the top shock mount and creating another one in a position where I can now fit a proper shock. I now have damping and pre-load.

NZ titles incl GP are supposed to be allocated at the AGM - if they've been asked for....

If no one asks, they're not allocated supposedly.

Just got back from a practice day at the track, the 50 performed faultlessly and I'm pretty pleased with the way it went. The new pit bike shock worked beautifully but my front brake still feels a little wooden,
( can't get the RS125 front end in fast enough )
The gearing is a bit out but not too bad.
I had one huge front end slide that should have seen me picking bits of bike off the track but the bike is so low it just seemed to sort itself out, made me feel like Valentino

Looking forward to tomorrow and race day.

Well Vale crashed in the 2nd points race re-mounted and finished behind his Nemesis (fast Fred)

We need more entrants in Auckland F5 as the turn out was rubbish yesterday, if it were not for team ESE bringing a spare it would have been pitiful.

Pro's for building an F5 bike

You can chuck an XL/XR/CB100 in a discarded FXR chassis and you have a very reliable bike that will not get you into trouble on the corners
You will be racing against riders who have been at it for years and wont take you out fighting over 17th position
The pace of a good F5 bike with a very good rider on board is not much slower than the same very good rider on his good F4 bike so saying they are too slow is bollox (29s on a 50cc fark)
You can buy an RS50 and build a very competitive bike for not much money ( A grade Tim very nearly took out the GP this year on one )
You can do what I did and buy an ancient Honda MTXR 50 and follow simple instructions and get 14 hp at the wheel
F5 riders are way cooler than F4 riders thus more attractive to the opposite sex
For 2T fans the bikes sound bloody awesome as they rev around 14-15K
They don't use much gas
For the trophy hunters out there you have a much better chance of getting one in F5 as apart from Nathaniel the rest of us are fairly mature

Cons

sorry cant think of any

Cons

Riding three classes is a killer.

You missed a couple of pros though

Riding F5 bikes at the slower end of the spectrum teaches you a lot about holding corner speed. On an FXR framed XR100 you should be holding the throttle wide from turn one to the horseshoe, then when you accidently hold it flat through the chicane on an F4 bike you work out that it can be done.

Run F4 and F5 and you get twice the track time for the same entry fee.

F5 bikes are way less physical to ride than F4 so you don't get as tired if you are a little unfit.

F5 bikes are huge fun.
