I geared a bit longer on my bike to overcome the lack of terminal velocity, and it made a big difference. Give a 44 a go. As you get quicker out of T12, you need taller gearing.

I'm getting 250 on the GPS at the end of the straight. 113 rwhp, and I'm only a few kgs lighter than you. I reckon it was running out of puff, as peak power is a fair bit lower than redline.

I saw the guys up the far end of the pits they are 'White Tiger Racing'.

I'm running 44 rear on the srad and getting just on 240 with 115rwhp and similar lard.

Mine shows just under 260 on the dial (15/45) and my GPS is around 225 on the straight as well. I'm running out of puff when I get to my markers. Interested to hear how your 44 goes.

Just looked my configuration up on gearingcommander.com and it reckons my top should be around 229 so that's probably not far off. 235kmh if I went 44 at the back.

Power wise I'm a smidgen over 100hp

Thanks for that mate. Very patient of you. I can't wait to get a good look at my arse for a few laps when I get to my computer after work tonight.

The broken iPhone just ain't cutting it.
Cheers,

Jamie

Thanks nick, I will definitely buy a 44t before my next outing. I was checking gearing commander vs my logged GPS max speeds. On the dyno my bike drops off at 14,500 and limiter is at 15,000. On the straight 225 is the exact speed gearing commander says for 14,500. I'm maxing out my top speed in 3rd between T3-T4 and T4-T5, but I can actually hit 15k down the hill from T3 (since its down hill). Going to a 44 will give me about 5kph more in each gear so I shouldn't have to spin it past 14,500 anywhere.

Having data is so useful! I've picked up so much from being able to video and time properly.

I can get you AFAM sprockets

Marty , What size rear are you running . i found 15 font ,43 rear and running a 190 set the gearing nice , revs just toping out down the straight and the top speed averaging around the 232 , best was a 238.

**chubb** · 30-09-2013, 04:30 PM

Doesn't running a 190 on a 5.5 rim pinch the tyre?

Thanks bob, I'm running 15/45 with a 180. You're a fair bit lighter than me though, ill start with the 44 and if I get good enough to top that out then ill drop another tooth. For me its not the main straight thats an issue (i expect to lose out a bit there), but the two spots i mentioned where a top out 3rd. Luckily sprockets are pretty cheap so it's not a big deal to experiment with.

not in my experience, one of the first things I changed when I got the suzi

**chubb** · 30-09-2013, 06:08 PM

Always thought apart from the dunlops

The rest gets pinched

What corner speed are you getting tipping into T4 ? when you top out in 3rd gear .

You just need to carry more lean angle

**chubb** · 30-09-2013, 07:50 PM

Yeah I still have chicky strips on my rear and front tyres... seriously not joking

Max speed between T3-T4 says 169 (thats banging limiter) and corner entry says 98.

I'm no pro nor anything but I reckon that if the Pirellis fit a 5.5 rim on STK600/WSS, they should fit the rim on my bike too!

**chubb** · 01-10-2013, 06:16 PM

Thought they use the 180/60

**Mr.Ed** · 01-10-2013, 06:27 PM

They do this year but it used to be a 190 if I'm not mistaken

**Marshy** · 01-10-2013, 08:58 PM

You'd be surprised about the actual width of various tyres, remembering that the profile plays a part too, along with tyre design in general (sidewall stiffness etc). Fourex ample, the Dunlop 190/55 GPAs are 188.5mm wide, whereas the 190/60 are 191.3mm.

Bigger differences are with some of the other tyres - the treaded GP rear (UK treaded) in 200/55 are only 191 wide (ie narrower than the 190 GPA). The Buffalo (US ntec slick) in a 190 are 188.5, but only 194 in a 200. And the awesome UK ntec rear slick in a 195 are actually only 191, BUT they are super high, so often don't fit in the swingarm without a new, longer chain!

On the front, the 125/80 Buffalo are narrower than the 120/70 KR106 (118 v 119). But then again, the UK 211GP treaded in 120/70 is 119, but the US 211GPA in the identical size of 120/70 is 123.

So there ya go! It's not all about the number stamped on the sidewall.
