140/80-17 on a NH

Postby rabidzoomer on Tue Dec 16, 2008 4:35 pm

The stock tire on the NH is a 140/70-17 but i want more of a sportbike tire since i ride my NH like a sportbike. I was wondering if if it would still go on. I believe that it would only be taller and it should have to clearance but i was just making sure. I wanted to order a new rear tire for christmas and have installed by spring so i can hit the track!

thanks

You probably can, but there are tires the right size that have more performance than the chassis.

Changing the oil weight in the fork, front fork braces, better rear shocks, would do more for real handling than a different tire.

Also, check your tire pressures.

The stock size works fine for the handling on these bikes.

A big handling boost for me was the replacement of the steering stem bearings. I replaced the worn ball bearing with tapered rollers. Cost about $35 and improved the steering, feel, and feedback immensely. I have stock Dunlops on now, had the Bridgestone BT045 before, and neither tire brand did as much as the steering stem bearings.

The tire will be the least of my problems getting better handling. Im planning on switching out the swingarm with a 600F4 swingarm with center shock most likely over next summer. Im also trying to upgrade to euro front forks.

It will be getting a huge facelift soon but for the time being that i have the stock swingarm and no welder i would like to get a good tire that i can still play with around town to and from work until i get my parts.

Zoomer, I recently put on a set of Michelin Pilot Road radials with a stock front size and a 150/70-17 rear.

They fit and handle great. You may wanna check them out.

I tried a set of Pirelli Diablo Strada's on my '97, using a 150/80-ZR17 on the rear and a matching appropriately sized front. I know, these are more of a performance-sportbike tire, but man they changed my 'hawk to a much more sure-footed ride and I love 'em. The point being that you can use the tires you mentioned, as far as fitting the bike.
