That's strange, because i asked about rear sprocket in local svc, and it's available separately. costs 450-480 something.

although they do try to sell full set. but it's upto you.

Oh, is it so? Thanks for the information...

Re: Yamaha FZ 25 Owners Reviews and Experiences

Of late, I have been facing rear wheel wobble. I was hit by a car back in August, and this issue has cropped up since then. I even replaced by swingarm shaft and bushings, but to no avail. Now, as I checked my rear wheel, I saw wobble in my rear sprocket. Even my wheel has mild wobble and it is affecting my handling confidence. I would have liked to post a video, but xbhp doesn't allow that. Kindly help.

A rear end collision can mean multiple sorts. But since you've observed a knack in the rear sprocket. What I'd suggest you to do is remove the wheel at a nearby tire repair shop. Get the wheel fixed in a truing stand and spin the wheel, this way it helps the wheel be free and helps you clearly inspect if the wheel or the sprocket is bent or worse, both. Try not to ride with a wobbly rear wheel at speeds, can cause uneven tire wear and loss of control.

Remove the tire, the tire wallah can do the rest for you. Do keep your observations posted.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I have completed nearly 2k kms, now it feels as if the handle or the entire fork assembly is tilted to the left (earlier I felt it was tilted to the right).

When I take my hands off the handlebar, the bike goes straight, but the handle/fork assembly seems to be tilted to the left. At slow speeds or after riding over a speedbreaker, the bike pulls to the left.

Any idea about what could be causing this? [MENTION=37035]ashwinprakas[/MENTION] [MENTION=33190]ashwanth.r[/MENTION] [MENTION=39214]B7ACKTHORN[/MENTION]

I initially thought that I was used to riding my CD100 which had this issue, but I rode my friend's FZ25 and it feels fine. I did report this during first service, they tinkered with the setting and said that it is fixed.

I just hope that I don't have to visit the SVC again and again like [MENTION=49147]Harrisoncool[/MENTION] did (I hope his bike is doing fine now after the assembly change).

Re: Yamaha FZ 25 Owners Reviews and Experiences

Anyone here changed front tyre size to 110/70? I want to know if it has changed the handling for the better or for the worse.

That could be because of triple tree alignment issues. I had the same observation.. ask the service center to adjust the triple tree alignment. One drawback i notice with front end of FZ25 is, with slight decrease in tyre pressure, handling becomes worse. So maintaining the tyre pressure is also equally important to have solid handling.

What happens when you counter steer? Does the motorcycle kick back? If Yes, then you have an alignment issue.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Has anyone changed the sprocket to make the gear ratio taller and thereby increasing the cruise speeds? If anyone has done that can your point me to the post? Please help

Echoing what Harris said, it could be a loose triple tree to handlebar alignment. It's like those good old bicycle days, where we fall, pick the cycle and we find the wheel is one direction and the handlebar is in another direction. This can be done at a local mechanic by making sure the alignment of the handlebar is perpendicular to the fork T stem assembly. The effect is more pronounced when the bike is ridden slow, good old physics at play.

Get it checked and adjusted and keep your observations posted here.

Never noticed this, will check it immediately.

This might be the reason, though on visual inspection it looks fine. I faced this on my Gixxer once, it was noticeable as the front tyre was not in line with the headlight assembly and the handlebar. Will check this too.

The problem is sourcing a .428 16T front sprocket, which produces gearing suited for highway cruising. We can also use a 43T rear for producing the same effect, but in this case, the chain length may be the spoilsport.

I'm planning to get a 16T sprocket of the XT250, but I'm still researching the compatibility.

Darn! I just re-read your original query and it seems rather than an alignment issue you have an issue with your cone-set, to confirm keep the motorcycle on its main stand and with the front wheel off the ground rock the fork legs, if you experience play then you'd need to rework your front end.

When I got the bike, the coneset was too tight and caused the bike to wobble badly. Perhaps this had a role to play?

Does a bad setting of the coneset cause the handle/fork assembly to be tilted to one side while the bike tracks straight (at higher speeds, say 25kmph+)? Asking because so far I have only read about the coneset being an issue when the bike pulls to one side or causes the front end to feel 'loose' and produce noise.

A badly worn cone-set can mimic alignment issues. I'm presuming you also get the "TAK" sound on hard braking.

As for sprocket'ing whats the stock configuration? Thumb rule is Rear/Front = 3.00 Optimum, over 3.00 means under geared and below 3.00 means over geared.

Nope, no sounds on hard braking. It's only the tilt which has been bothering me as it causes my left palm and shoulder to ache (apart from the usual irritation).

Stock is 3.067 (15/46).

Then do post result after doing the cone-set free-play test. I have a strong feeling that your cone-set has gone for a toss.

Stock is 3.067 (15/46).

Keep it stock, at best you can drop a teeth at the rear but then that isn't worth the effort.

My stock setup was under 2.6, was a pain to ride within Kerala(Can't go beyond 3rd gear) so I had to change it to 2.85 to make the motorcycle usable at the least. Next time I'll be going for the Duke 200 4 Hole 14/42 setup on my P220 to get a perfect 3.00. As for the current setup at 2.85, the FE has not changed if not gotten better and the top speed is more or less the same at 130+ kmph on the speedo, only difference is that the engine runs at a higher RPM doing the same speeds.
