Its 2017 so I thought I would bring this up for any 750 owners still out there. Wondering what tire choices you have made, especially for track days. I have always run Michelin pilot sport then powers on my bike with 120/65 and 190/50. The more I started doing track days, I switched to a 180/55 rear. I like that set up and if it was good enough for the SPR, its good enough for my bike.

So now we are 17 years later from when the f4 debuted and the 65 series tire is getting very narrow in the selection pool. I'm thinking of going up to power 3's but alas no 65 front. the 2ct are avail in a 65 front. So, I'm trying to decide whether to get them, or step it up to a 50/50 tire and use a 70 front. researching 5-7 year old threads, some have had success switching over, but more have said that the handling isn't as sharp. I even found a thread where a 1000R rider wanted to try and 65 front. MV adjusted rake, bar height, and rearset height along with the 70 front. I would assume it was for a reason, and don't want to have to make that many changes as I KNOW my bike the way its set up currently.

How many of you have made the switch and what are you thoughts? Especially for the future which has 90% of bikes running 70 fronts.

Had a 190/50 on my Aprilia RSVR hated it, went 180/55 and won't change
You're sort of stuck ......only a couple bikes came with 120/65 tires everyone else went 120/70

So choices have dried up .... join the crowd!

Yep...that seems to be the story. I'm going to stick with the 65 and give the Pirelli Rosso Corsas a try and get a set of Power 2ct's for my other set of wheels. that should set me straight with tires for a while.

Well I have since Years a 120/70 and a 180/55 on my 2001 F4S.
My experience is that I love and enjoy the, in my mind, sharper handling of my bike tremendously.
Now that could be also down to the top canyon carving performance of the Sport Attack 2 tires I ride.
And then don't listen to others give it a shot and try it out for Yourself.
We talk here about 400 dollars for a lesson.

I'm running the 2CT 120/65 FRONT 180/55 rear. Quite a nice tyre for the road. They went okay on the MV at Eastern creek on a hot day also (36deg C). Plenty of feel, and predictable slide. Got about 6000 on them now and they were alittle squared off in the middle until i went into the hills last week. Generaly I run Q3s on my R6 trackie. But about to try out Metzlers racetek RRs.

My main concern is the 70s hitting the radiator guard and the leading edge of the side fairing. And they do. ...

Hey Haupti, Which brand 70s are you using? I know some are smaller than others and don't have the same clearance issues.

I run Conti Sport Attack 2 on my F4.
Nothing is rubbing on anything on my bike.
The F4 1000S has the same bits and pieces and runs 120/70 I believe.

to compensate for/work with the 120/70, the 1000S adjusted the rake, raised handlebars and higher rearsets that adjust even higher. I had some on my bike and went back to the original rearsets which were more comfortable.

I've decided to get 2 sets of tires. Power 2cts for street and Pirelli Rosso Corsas for track only duty. Both come with 65 front. I have 3 sets of wheels, so on the 3rd set I may try a 70 series if I'm dissatisified. if I ever get to do enough track days where I want more race rubber, I'm going to have to switch, but I doubt i'll ever hit the point where the tires are holding me back more than balls.

Thanks mate, I thought the 1000s had alittle more rake?
