tires and turn in?

Finally have my '92 finished and on the road. Bike came with dunlop 207's. I find the low speed turn in (or maybe you would call it front end tuck) waaay too responsive. Since I will replace both front and rear rubber I could use input as to what tires might reduce this trait. Thanks. Oh and btw those dunlops are sure greasy when its cold out. Forks are set to factory height with new fluid, rear preload set for proper sag, head bearings checked and set to spec and no slop in rear swingarm pivot.

207s and michelin pilots are generally V shaped and have the fast turn in that many folks like. For me, I like a more progressive turn in and go for a more U shaped tire. Pirelli Diablos, Rossos or Bridgestone BT14 15 or 16 as well as Metzlers are more U shaped.

Thanks, thats the info I needed. Had the bike out yesterday for a 60 mile romp, man that v4 likes to sing, I think officer freindly would not have been too impressed.

indeed,

was out on mine yesterday with several romps into 11,000rpm+ range for a winter "texas tuneup"... wandered upon an accident - some kid (18-19) in a car ran off at 70mph into a brick driveway abutment. He tore the bottom out of his dodge neon and dropped the motor in the middle of the lane. Both airbags deployed and he was a bloody mess but otherwise OK, I helped him out of the car and called 911. Normally I would have left him in the car, but there was tons of smoke emanating from the car and lots of fluids, I didnt think it prudent to leave him there as it risked catching fire. 5 mins later the cops, fire and ambulance showed up... I think he will be ok. left the scene once the VASP showed up and took control.

ride was sadly over as I lost the feeling... too bad, was 65+ degrees in NoVa

 

Well said, go for the Pirelli Corsas IIIs It's a great tire

 

This situation can be caused by the tire profile as well as, insufficient trail. Without changing tires, this can be rectified by reducing the trail, via suspension adjustment. This can be accomplished in a few different ways.

1.) Lowering the rear ride height....which i'm pretty sure isn't applicable unless you have an aftermarket shock that allows for ride height adjustment.

2.) Reducing the rear preload

3.) lowering the fork tubes in the triple clamps...lowering the tubes 4mm will increase the trail approximately 1mm

4.) Adding front preload

I would experiment with dropping the fork tubes in the clamp in 4-5 mm increments until you get the feeling you are looking for. Do not lower the tubes so that the fork cap is below the lip on the top triple clamp. If it starts to feel better, but it is getting close to the limit of adjustment, then try also adjusting the front and or rear preload.

All of these things can effect the front end feeling upon corner entry, Just something to think about.

 

DCIIIs are good, but they don't come in a 170

 

Thanks again. I had not thought of lowering the fork tubes below the factory marks. It seems all the rage today to raise the fork tubes until the front fender starts hitting hard points under heavy braking. As I asked in the first post, my concern was reducing low speed turn in, and betarace's tire profile suggestion along with norcalboy's chassis ideas should give me plenty to tinker with now the temps are back in the 40's here in MS. Also, added a couple pictures of the finished bike to my photo gallery for member entertainment.

You are correct sir, but you can put as I do the III on the front with the standard Corsa on the rear, which does come in a 170 size Wa-la.. or you can shoe horn a 180 on it, but don't think you'll be able to scrub in the side walls.

 

Ruh Row I sense a tire thread evolving but will ask anyways, will a 180/55 clear the swingarm.
