Title: Conti Road Attack Tires and Stock Wheel
Post by: oracleofmist on February 17, 2009, 06:55:54 AM
Hey guys,

I am going to be getting a new rear tire as mine is all worn out. I saw on the wiki that the Conti Road Attack  140/80 tires are great, however I have a few issues.

1. Will they fit on the stock wheel? I am assuming they will, with no difficulty since they are recommended so well on the wiki site.

2. Where can I get them. I have been through a few sites and can only find 150/80 and not any 140's. If someone knows where to get them that would be great. If you can't should I get the av46 140's or the lasertec 130/70's?

There is no 140/80 RoadAttack tire.  I used a 150/70 on my stock 3.5" rear wheel and ran it with a 110/80 Lasertec front.  Still think they were the best handling tires I've had on my GSs.  I use bias and radial sport touring tires and don't use the stickier but shorter lived supersport types.

The only 140/80 sport touring radial tires I can think of are the AV46 and the Dunlop D205.  A 140/80 is shaped for a 3.5" preferred rim width and the 150/70 RoadAttack has a 4.0" preferred rim width but is approved for 3.5" fitment.  My RoadAttack:

So  I shouldn't have any issues mounting the road attack 150/70 on my stock 06' wheel. Yay, I'll order it for sure then :)

I heard that if you mount this tire it sqwishes the tire over the rim and makes it harder to corner? I also hesrd it doesnt make it any wider it just pushes tire up so it makes it taller? Do you have a picture of this tire mounted in a side view and is any of the above stuff have any truth to it, as i am also thinking about getting these tires or the BT-090

It has nothing to do with the tire brand/tread pattern, it's all in the sizing of the tire. I have Avon Road Riders on mine in the same exact size 150/70-17 and the stock rim doesn't change the geometry of the tire itself. The more narrow wheel does pull in the sidewalls a little more but if anything that would make it easier to turn because it would place your sidewall at a more upright position with your angle of lean.

I just scrubbed in my tires a bit today and I wasn't taking too severe of turns.. no knee downs or peg scrapers... and I have about 1 inch chicken-strips on the back. (Strips of clean rubber on the tread before the sidewall where the tire has not touched the ground.) At no time did I feel "unsafe" or that the bike was any harder to turn than when I had the stock 130's on. If anything, the bike felt MORE stable and more PREDICTABLE in turns than with the stock 130s...

Here's a pic from the side... they do look much taller than the stock tires.

From they back, they don't visually seem much wider.

if i put the conti road attack tires on will i have to bend the brake torque rod?

Also, has anyone ever used the BT-090 as a street tire? i know i wont get great mileage but just want to know how they handle on the street appose to the track?

You may have to bend the rod... I did just out of caution, but all it took was 2 wooden blocks and a sledge to the center and that knocked it right where it needed to be.

Um... those are kind of a bad tire if you're not going to be doing A LOT of highway riding. The compound is very hard and takes a long time to warm up as opposed to a regular (road/touring) tire. That and the pitch of the tire is very steep. Basically what this means is that you have to ride a little longer before really getting on the throttle or doing any hard braking, and as for corners, if you don't have a front tire that's matched to the rear tire profile, you may feel a slight ducking effect... basically it feels like the rear tire wants to drift out.

Like I said, kinda a scary tire on the roads without proper warm-up.. but hey.. it's your bike! :)

You talking about the RoadAttack or the BT090?

BT090... :2guns:

Road Attacks are perfect for our bikes.

Has anyone. Used the BT-090 for street?

The problem is is that they're a purpose built tire... they're meant to be a supermoto tire... (meaning a dirtbike with slick wheels) so they're going to be high-speed (V and higher) rated... most of which (I believe ALL BT-090's) are RACE profiled tires... meaning they're shaped like a V with a very steep point in the center and slanting curves down towards the sidewalls...

Again... since these are RACE tires they are of a VERY VERY HIGH DENSITY RUBBER and are NOT RECOMMENDED for NORMAL STREET RIDING....

I hope that you DONT get them because they will NOT BE COMFORTABLE unless you're planning on riding your bike ON THE TRACK more than on the street.

GET WHAT I'M SAYING???  Lol. Sorry, had to.  :cheers:
