I hope this is the correct forum to ask this.
1: What would be the same size slick to a 190/55 Power race.
2: What are youy opinions about a 195/70 Dunlop slick.
Thanks for your help in advance.
Power race vs. Dunlop slickscwr1 06-29-2008, 09:10 PM I hope this is the correct forum to ask this.

Thanks for your help in advance. nossliw 06-29-2008, 09:53 PM I'm suscribed... I ran the 190 michelins and just got a set of dunlop slicks for the track after trying a set of pirellis slicks that were by far the best tire I have ever ran but I'd like to know between the dunlops and michs... Next on the list are mich slicks... krazy8 06-29-2008, 10:19 PM :fork Bump...To a ? that I can not answer...Anybody... gfracerx 06-29-2008, 10:34 PM :hellobye: subscribe glennwyatt 06-29-2008, 10:35 PM i've rocked 2 sets of the big dunlops 195/70/17 rear and 125/80/17 front, on the street and absolutely loved them, they seem to survive the heat cycles without getting too hard and are super sticky once warmed up. plus the profile of the tire is amazing in the corners , just tons of grip in the corners at super high lean angles nossliw 06-30-2008, 07:44 AM anybody... for track...heat cycles? Wear? Greasing? JPWarrior 06-30-2008, 09:51 AM I would never run slicks on the street. Modern street tires perform much better than race tires on the street. You don't have to worry about heat cycles and tires coming to temp. Althouh they are gonna give you more grip when at temp, the odds of you being at temp are far less than if you were on the track. Also, you wouldn't want to get caught in the rain with slicks.
I personally run this tire combination on the "TRACK" and I like it more than the Power race setup. These tires are very predictable and last a long time. You can lean, lean, lean and it's amazing how much grip they have. They do take a little more muscle to move around on than the smaller tire combination but the benefits outweigh the negatives IMO. I'm able to throttle up earlier in corner exits cause the rear tire has more contact patch than the 190/55's. I can generally get several trackdays on mine before needing to change them out and will push it another day while sliding the rear around. The fronts wear very slowly and still maintain good feel and predictability even when you think they may be shot. My tire guy has indicated these aren't as suseptible to heat cycles as the Michelin's. I still keep mine on the warmers anyway so I can't offer advice on this.
Keep in mine if you swap out to this tire (195/70) you are gonna have to adjust your suspension to compensate for the geometry change this tall tire is gonna do to your bike. As well, depending on the year, you will have to get a longer chain or smaller sprockets to allow the tire to fit in the swingarm. This tire expands quite a bit and if you don't have it set back in the swingarm it will make contact in the front and roast your tire. For the 04 and 05 guys, they run the smaller sprockets and move the tire back in the swingarm. The 06, however has a slightly longer swingarm and you can move the tire back a bit further.
If you do swap out to this combo, get the Graves, lowering upper shock mount. You will have to slide the forks though the trees to compensate too, because even with the lowering bracket the front end will still be too high and prone to serious headshake and high speed instability. My lower tree was shimmed down and upper tree had the shim removed, to help compensate for the geometry changes.
I'm trying to recall but there's another guy in the racing forum who runs this tire combo. I know his real name but his forum name is eluding me at the moment. Lars is his name.
I'm sure he'd have a lot more info useful to offer, regarding tire wear and heat cycles. blur1 06-30-2008, 04:49 PM lol, you are talking about fiveoh!:lol
and i also run dunlop slicks ...but only at the track and i have also used michelin slicks....but i prefer the dunlop in the slick. it is almost the 'perfect' tyre.
and as stated..use street tyres on the street !....there is a reason street tyres are called 'street' tyres!:yesnod JPWarrior 06-30-2008, 08:27 PM lol, you are talking about fiveoh!:lol

No disprespect to Lars.
Getting older is cruel sometimes.:crash nossliw 06-30-2008, 10:11 PM Good info... I was very pleased with the pirelli slick last race day and I have been running michelin power race last year on track days.... I have a set of Dunlops on the way and am very interested how they will hook up. 190/55's. Like I said the pirellis blew me away and I could accelerate harder without any slip whatsoever.... got into trouble coming into corners with to much confidence though.
Appreciate the info JPWarrior cwr1 07-11-2008, 08:55 PM I know its been a while but that was great info. I did jump to the slick and had a track school at Thunderhill and i must say i felt very confident on the dunlops. I also had to get a longer chain to accommodate the tire but i didnt adjust the suspension. I had it adjusted the last time i was at the track with Catalyst Reaction and i thought that i would need it again with the new tires but the funny thing is i didnt. The bike felt better with the slicks. The next question i have is what would be the difference going from a 195/70 slick to a 195/65. Will it affect how quickly it turns in corners or the contact patch. blur1 07-11-2008, 09:09 PM Will it affect how quickly it turns in corners or the contact patch.
it should effect both.the higher the profile of the tyre vs the width = a more triangulated profile. thus making both contact patch and turn-in 'easier'. but it might adversly affect stability? it's such a small change that it depends on the rest of your bikes setup and your riding preference and track layout. trying them and evaluating for yourself would be the best judgement JPWarrior 07-17-2008, 10:34 AM I know its been a while but that was great info.

I don't believe it will make all that much of a difference. She may drop easier for you because the 70 is sooo wide it fights initial turn in. The 65 may be easier to handle...:dunno?
If you haven't changed you geometry at all with this tire change, you really should look into it. The 195/70 rear tire raises the rear quite a bit and if you don't lower the rear and raise the front you're gonna be more prone to tuck the front end in a turn. Both rake and trail are reduced by this much of a change.:fact DanQ 07-17-2008, 10:50 AM Good thread :thumbup
JP is (again) spot on with the changes that should be made to the chassis in order to avoid headshake or tucking the front. Predator04 07-17-2008, 12:02 PM I hope this is the correct forum to ask this.

I dont say this only because Dunlop supplies my tires but beware of the power races. When they reach there wear limit they lose all there traction, one lap youve got great traction and the next you are slidin all over the place like you are on a sport touring tire. I am not jokin about this a friend totalled two bikes in two months at the big track at willow springs because of the power races. Oh and the tires you are comparing are for very, VERY diff level of riders. ViperRy 07-17-2008, 01:12 PM I run the big dunlop slicks... only knocked off one link of the DID chain so the wheel sits back pretty far. If you get the NTec type then expansion is not that big of an issue. Non Ntec and you get a bit of swelling. Setting your suspension for these tires is a must. I made the mistake of switching to the smaller profile Dunlop DOT Race tires for a run and not re-adjusting the suspension (I got lazy I guess). cwr1 07-17-2008, 02:22 PM So what do I look at getting. I looked into suspension setup and there seams to be a few options. JPWarrior 07-17-2008, 04:20 PM I don't have the exact measurement changes. What you need to do is some measurements stock and with the new tires. You won't be able to lower the rear adequately so you'll have to add the difference from stock, back to the front to keep your geometry the same. Most people use the graves lowering link at the rear, but like I said, it won't give you enough. | |
