hmm I reckon the 50 would have been getting close to 140 at Ruapuna, I'd have to measure the rear tyre size again & calculate it. A real flash 100 should touch 100mph, but I can think of only 4 bikes. But yeah on a go kart track esp Mt Wgtn fast speeds are unlikely.Originally Posted by wbks
Don't you look at my accountant.

Maybe I should have made it clear i meant go cart tracks lol
I'm quite surprised 50's go so fast. I've kind of been thinking of the cheap 50's you buy now that max out at 60 though

Team ESE bike's are about 117-120kmh at Taupo, 86-94 depending on who's riding and which way they are going at Mt Wellington and pretty much the same or a little faster, possible touching high 90's clock wise at Tamuranui.
I found the speed of the tight infield turn at the end of the sweeper (clockwise) at Tamuranui took some getting used to. I just soo want to get back there, its such a blast.

Was that your GP doing 120, or one of the slower ones? My 50 wasn't a match for the 125 so maybe I wasn't that fast after all, just at Ruapuna I was running another tooth on the countershaft. 'Seat of pants' I would have thought I was getting high 120s at Taupo. Maybe I was well wrong. If you trust the measuring device. My std road RG50 did 105kph on the flat (whilst indicating 115).

What did you do to the rg50 to get it to 120+?

I skimmed the head & polished the ports

I should have said the speeds at Taupo were recorded last year, this year my speedo failed and you and I were out in front of the other ESE bikes.
Speed was recorded with Cateye Velo 5 or 8 bicycal speedo's. They record/hold the max speed.
How good are they? so, so I expect, but in agreement by +- 2 or 3 k's and are set up by entering the wheels rolling diameter.

Be fair, I also saw you leaning forward and low to cut wind resistance.

What realy frightens me is your 50 has the legs on so many F4 bikes whatever the circuit.

Hey I did the calcs & I'm absolutely full of it. Seems you do need a longer straight to get these things up to top speed. Seems at Ruapuna I would have been cracking 120 but Taupo only 112. I was over revving at Ruapuna so it would deff pull taller gearing & that was unfaired. The NZ record for a 50 is 140k, but that was specially set up & running funny fuel, but I'm pretty confident that my bike on av would get similar power. More if I set it up. Sadly my bike is rebored to within bucket limits, but for a speed record attempt it would need to be exactly 50cc or less.
My 50 was faster than many F4s because it was leaving the corners 10kph faster than a few & carry that head start in speed down the straight.

I recon your right, my 125 at Pukekohe with the longer straight and slight down hill to the hair pin gets me into the high 140's possible even 150 ish depending on the wind, so you could be easily pushing 140's at Ruapuna. Thinking back I recon I was over geared at Taupo.
