F4 & F5 GP 2011, Taupo Track 3, 6 November

[Trudes]

It is interesting that the top 5 or 6 in the results are on standard chassis bikes with small suspension upgrades only. I am not in so much hurry to put an engine In a super stiff frame made for much more power. Flex is a good thing. Heaps of feed back from the bike. I remember talking to Kyle H about riding an rs125 and him saying you don't get much feedback from the bike. It's ether on rails or on your ass. Not sure if others feel the same but food for thought. I remember riding fishies bike an thinking If felt like a sold block of ice. But I spoze it works for him. Might be better now. But one thing is for sure bikes and riders are getting faster all the time. It's good to see.

Rich, you must have a ride on Rangi if you like a bike with 'flex'.

Its pretty clear, that if a good rider bothers to build a fast stroker they could dominate the longer tracks.

A bold statement if I ever heard one. I hope someone will back it up.

Why is it so clear?
You've had Avalon riding for you for a while now, is she not fast enough?

Once some of the faster four stroke riders decide to get serious and build a fast bike and more so a fast chassis, you wont see which way they went? Stock steel FXR and CBR frames from an Asian commuter bike? Nah ditch those and get something lighter and better handing.
Seriously, the four stroke brigade have only just started. And you must realise by now that you need more than just peak power to build a good race bike?

Valid points.

One day. At this point going riding is the last thing I want to do. My back is so fecked. No riding for a while.

If you do the numbers you will see the 4-strokes are clearly getting close to what is practical but the 2 strokers still have much more room for development at reasonable cost.

Have you seen what the stroker girl and boys are starting to turn up with.

Yes agreed, you have to ride fast to be fast, so it won't be me winning the next GP, but I think the 4-stroke boys need to get their skates on or some good rider out there and there are a few of them around the country will show up with an all conquering stroker soon.

I know it won't be me winning the next one either. The guys / gals that are fast won't be doing it on HP alone, handling and skill have a lot to do with it, yes on a long track power is much more important than on the kart tracks we usually race on up here but even with a slower bike there is a truckload of fun to be had. I had ball at the GP, in both races, even though I got lapped by the field in F5, including by my wife. Would I have got a better result if F4 if I hadn't run in F5 as well? Possibly, would more power have helped, probably, would I do it all the same knowing that I was going to be lapped by guys I can usually beat at Mt Wellington? Absolutely.
There were about 6 people at Taupo with a shot at the number one plate, the rest of us were there for other reasons be that catching up with mates from around the country or to work on the development on the engine type of their choice, the whole two versus four discussion is an interesting distraction but doesn't have all that much bearing on what goes on on track.
If Andrew had been on a fast two stroke would he still have won? Can't honestly say but my money would be on him being at the front scrapping for it. It really isn't all about the bike.

And you think the four strokes don't? Most are still running standard chassis, brakes etc. A lot of weight could come off some of these bikes yet.

Sure have, a couple of them are being built down here, but once/if they start cleaning up, a bit more work will go into the four strokes

All I can say is they are going to be pretty special to beat the current crop, but it would be good to see them in the mix, thats for sure.

Agreed, anyone at the pointy end of F4 is pretty special, I am picking a stroker or two will join them soon.

I certainly qualify as a stroker and I'm going to be footing it with the top guys at the next GP.

Or having the bike die because I've tried to squeeze out too much power with too many shortcuts.
