Rule of mechanicals. The less you fiddle the less problem you get. So don't touch unless any problem arises. That's my mantra.
As a result my joy is still like new even at 4.15 Lacs.

Re: Yamaha FZ 25 Owners Reviews and Experiences

My stock mrfs have squared off pretty bad after 20k km. What tires do i use? Looking for a pair within 8k. Decent grip in wet and a mileage of around 15k would be good. Looked at Michelin Pilot streets, pirelli angel ct and the sport demons. Anyone using one of these on their fz? From what I've heard the pilot street radials are the best bet, but i'm not sure about the price on those. Heard some bad stuff from long time angel ct users too. No idea about the sport demons. Also looked at the diablo rossos, but those wont last as long and are pretty pricey. Please help me out!

On a side note, has anyone changed one of their sprockets? Im looking to get the front sprocket up 1 tooth. Should bring down the rpm for 100kph from 6.5k to 6k without sacrificing on torque too much. (Although im not sure how hillclimbs with luggage will be affected)

Re: Yamaha FZ 25 Owners Reviews and Experiences

Regarding tyres, Michelin Pilot Streets are indeed the best option. You need to extend your budget by about 4k for a pair though, but you will be left grinning. Brilliant grip all round.

Regarding increasing a tooth in the front sprocket, yes torque will increase, but you'll compromise on your chain life. And yeah, what's the point in more torque? Isn't the bike torquey enough for you?

Re: Yamaha FZ 25 Owners Reviews and Experiences

Please correct me if im wrong, but i think increasing a tooth on the front will decrease the torque. I just think itll be ok to lose some torque for a little lower rpm at cruising speeds.

Ok i've found another tire now. Its called the Metzeler sportec street. Anyone have any experience with those? Metz claims they are long lasting, reviews say they channel water well, and price says they are in budget too. Michelins are out of budget, can probably get the rear one, but will have to put a sport demon or something in the front with that. Not sure how that would work out..

Re: Yamaha FZ 25 Owners Reviews and Experiences

You can get a 16T sprocket of the XT250, or get a custom one made. I had planned to do it, but didn't go through with it. With a 16T front sprocket, you'll effectively lose some acceleration and correct the speedo error to an extent.

Re: Yamaha FZ 25 Owners Reviews and Experiences

you can try Pirelli Angel CT instead, pretty much same grip but it's newer stock and available in 100/80-17 also. a set will cost you less than 7k.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Does the tappet noise reduce by using 7100? After 5k rpm tappet noise is very loud

Re: Yamaha FZ 25 Owners Reviews and Experiences

What's your odo reading? Depending on that, you may need to adjust valve clearance, or check your cam chain tensioner for slack.
In my case, tappet noise was reduced after adjustment of valve clearance.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I have a Fazer 25, like you I also have similar feedback for this machine but my only gripe is that rattling noise after 5K RPM. I am ok with sound (as nobody has been able to get rid of it so far) but at least want to know what the F is rattling in there.

----consecutive posts auto-merged-----

I also got the valve clearance checked, tappet setting done...noise was reduced by good margin but again it has come to the same level as it was earlier after riding 300 Kms. It is not tappet i believe it is something else.

Re: Yamaha FZ 25 Owners Reviews and Experiences

My odo is around 23k. When I get the bike serviced, it'll be less and gradually increases as more km are done. Does oil has an effect on this? So only asked weather using motul will reduce noise or not

----consecutive posts auto-merged-----

Someone had earlier said that the rocker arms are set on looser side to increase longevity. Maybe noise coz of that. But there is no permanent fix I guess. So only I use full face helmet where it blocks the noise and ignore it.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Disturbing thing is that we are so precise about everything that relates to our motorcycle & here we are OK with the guess work about something that is directly related to the engine & constantly reminds us with the rattling noise. Neither there's a solution for this nor anyone can put a finger on the part that is actually making the sound. It amazes me...I try to ignore it but sometimes it becomes difficult, as I have switched from Hero Impulse to Yamaha, Impulse was so smooth & noise-less at any RPM, I rode 990 KMs in a day on it yet it never made any tappet noise. I miss it!

Re: Yamaha FZ 25 Owners Reviews and Experiences

I don't have an Fz-25, but I've been using a set of Pirelli Angel CT on my Pulsar RS 200 for the past ~4k kilometers.

I haven't gotten a chance to test the wet grip, but the dry grip of the tyres is very good, assuming that there is no gravel/dirt on the road.

Compared to the MRF zappers they replaced (at 21k kms), the Pirelli's were a lot more stable on uneven roads and the white lines (where the zappers used to feel unsteady).

I can definitely feel the road more with the Pirelli's compared to the MRF's, which can be good or bad depending on how much you value comfort vs confidence in corners.

I havent had any bad experiences with them (yet). They a pretty good set of tyres for a fair price ( just under 7k rupees).

Re: Yamaha FZ 25 Owners Reviews and Experiences

i have already told you man, the noise comes from balancer, why it happens in 5-6k range ? i don't know the truth. but that's what the Yamaha engineer told us in free monsoon checkup 7-8 months ago. and he didn't explain in more details but assured us that it's nothing to worry about.

After that i did some searching on xt250 engine noise as that's the bike this engine is taken from. the engine was originally launched around 2007, with carburetor and no oil cooling which produced around 17ps/18nm. since then engine has seen many small tweaks here and there such as oil cooling, fuel injection, changes in intake and exhaust port, thus after almost 11 years now this engine makes 21.6ps/20.6nm (Brazil fazer25). but one thing that has remained same is the rattling noise it makes around 5-6k rpm range. so if it was really an issue apart from the noise , i think Yamaha would have already fixed it in 11 years.

i agree it doesn't make sense when we have many other bikes which doesn't make this kind of noise. but there's literally nothing we can do about it.



that's the part where noise comes from, i think that before 5k rpm those compression springs ( #part 21) don't fully compress, and around 5-6k rpm, it moves between non fully compressed to fully compressed position within 1 revolution thus generating rattle noise. after 6k rpm it becomes fully compressed and that noise goes away. now Yamaha could use better springs there but if those doesn't compress enough in lower rpms, bike will vibrate a lot more. i could be totally wrong here but that's my theory behind the noise.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Yes Slopegatri, you did tell me & because of your logical reply I was OK with whatever concerns I had. Now also due to your original reply I am able to accept the bike the way it is otherwise it wouldn't have been easy for me to let it slide. This long reply of yours does help but Yamaha people act as if there should be no rattling noise & they friggin act to help you fix it instead of acknowledging that this is a GENERIC issue & it will not threatened engine or our safety. As I said I am willing to accept the characteristics of machine provided it is established that it's not going to harm. I hope you get my point or rant (whatever you may make of it buddy).


A big Thank you for your efforts to always give me the best answer.

Re: Yamaha FZ 25 Owners Reviews and Experiences

No problem man, i understand it's not easy to accept these kind of issues.
