Track Wets
« on: July 02, 2013, 07:54:56 PM »

I know this kind of thing always opens up a can of worms.

Might be taking a GT125R on a "silly" outdoor go-kart karting track, versus a few peers with XJ600Rs, GSXR750s and GSF600s. I've proven myself quicker through seriously twisty rural roads (though I get left standing anywhere else) the kind of roads built alongside twiddly meandering watercourses, and I'd love to repeat outperform on the track. The only thing is, rain exists, and on the current rubber I've had a few slithers and wash-out so I've lost confidence.

What're the best black rings I can fit my bike with for wet-weather footpeg-scraping?

I don't know much, but I think I want something with a water-dispersing tread and a soft compound that heats up easily. Durability unimportant as they've only got to last a weekend.

Cheers!

Front
100/70
120/70

Rear
125/70
160/60
190/60

You will struggle to get the right size tyres for a Hyo in racing wets. However we race on a control tyre, Diablo Rosso II's as an all weather tyre and I can still get me knee down in the wet no problems.
Another problem you can run into is generally the guys who stock racing wets won't sell them to someone who doesn't hold a racing licence or attending a track day they are operating at.
The moto3 100/70 will fit on the front no problem and you will actually get to the edge of the tyre. The Moto3 125/70 rear is just to narrow, anything smaller than a 140 and you will begin to roll off the edge a 160/60 is your best bet although it will create handling problems when coupled with a 100 front due to the sidewall distortion when fitted on the rim.
Unless it is torrential rain with standing water, it has been proven time and time again that wets provide minimal benefit over a correctly chosen grooved tyre in the correct compound. Plus they will just burn apart and it feels like you riding on jelly if there isn't enough water around to keep them within their operating temperature, which will probably set you further back with your confidence.

I'm glad I asked!

I was looking at a Diablo Rosso II for the front as they come in 110-70/17 standard size for the bike, and an Angel ST for the rear as that is available in 150-70/17. I can't get Diablo Rosso II in a rear size, and can't get Angel ST in front size. Angel STs are marketed as being able to have a bit in the wet.

But I was looking at these for the road rather than racing. The racing thing is just a fun day out, nothing serious, and I'm only assuming rain because it always rains when you make outdoor plans. That said, if they're okay to use on a twisty little track (we're talking speeds of 40 or 50 at best) and will still go on the road, then I needn't bother with specialised track stuff at all.

Currently I'm on Avon RoadRiders, which are marketed as a "general purpose" and for "everyday use" on "midrange bikes" and the pair that're on the bike must be at least a year old, and I've done 5000 miles that I know about on them. Decent enough in the dry but have given me white knuckles in the rain. The only way is up.

If it is just for the raod go with the Diablo Rosso II's. Amazing grip in the dry and good grip in the wet. As I said, on the track I can still get a knee down with the Rosso II's no hassle. Expect only a few thousand Km's out of them though.
They don't come in the standard size for the rear but the 150/60 will knock about 8km/h off the top end and you will gain a few hundred revs more when cruising. You can compnsate with going 1 tooth less on the rear sprocket. I run a 140/60 rear for racing as it provides that largest contact patch possible and I can get right to the edge of the tyre where a 150 you can't, even with the stand cut off at the frame to give more clearance which allows enough lean angle for the fairing to scrape on the ground.
Another very good option is the Dunlop Alpha12 or Q2 spormax tyres. They come in standard sizes and are probably a better option for the road, has about 95% of the dry grip of the Pirelli's and the same grip in the wet, only the dunlop's give warning when they are about to let go, where the Pirelli's just let go, as I just found out the hard way onthe weekend.

Eep.
I'll probably go for the Dunlop ones, then. The idea of going without warning is as fearsome on the road as it would be on the track. Grip is lovely while it's there but a little bit of handling at the limit to let me know I'm being ridiculous is exactly what I need. Also thanks for the tip regarding the size! I will put the benefit of your experience to good use.

I run a 140/60 rear for racing as it provides that largest contact patch possible and I can get right to the edge of the tyre where a 150 you can't, even with the stand cut off at the frame to give more clearance which allows enough lean angle for the fairing to scrape on the ground.

I did wonder about this. With the 150 in the dry I can get right down, but still get the obligatory ribbing "hurrhurr chicken strips lol" because I haven't been able to reach the edge, and frankly don't have the courage to lean over any more than I have been doing purely for the sake of peeling rubber of the edges, as I'm scraping stuff already. My more-dedicated race bike (currently in bits) also uses the same size rear as the Hyosung, and I can pretty much reach the edge of that one because the bike is so narrow, and ludicrous lean angle was one of the top priorities when it was designed in the power-crazy 1980s. That's on cross-ply MT75 because the bike is so light, probably 70kgs lighter than the Hyosung, and has 3 times the power.

I'll see if I can get some photos/videos done of the day when it comes round too.

Yeah. Slightly enhanced Italian 2-stroke race bike. Bit like riding a ballistic missile.
