Re: Yamaha FZ 25 Owners Reviews and Experiences

Mercury visors are not illegal in Chennai if my memory serves me right. Though tinted visors must have minimum light passability of 70% usage of such visors in night and dusk can hamper visibility, especially black visors. All tinted visors are meant only for DAY use. You will be fined with a tinted visor abroad at night.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Hi xbhpins, I purchased a Balck fz 25 this Saturday, paid full amount by debit card and gave them all the documents. I even selected my bike and noted the engine and chassis number. To my surprise the Yamaha showroom guys told me that they can not give me the bike until RTO passing!! They say it's a new rule, you can't get the bike until RTO passing, they started showing me some notification in Marathi which I didn't understand. Is this really true or they told me a lie?? Place of purchase, Wagholi Pune.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Upgrading to Stainless steel braided brake hose will surely help to some extent. I didn't yet installed. Will look at it after a year.

Actually the brake pads are smaller than front and operated by one big piston. In front there are two pistons. Yet to find out if this can be upgraded to bigger caliper and pads.

Update: Spoke to an expert. Bigger capliper is not easy. Master cylinder can be change for more pressure. But easier option is better brake pads, sintered ones, and steel lines will make lot of difference.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I would rather suggest to look for better brake pads first before going into mechanicals.

Stock Brake pad material?

Re: Yamaha FZ 25 Owners Reviews and Experiences

You mean you're not sure if Mercury or Rainbow coloured visors are illegal or not?

Re: Yamaha FZ 25 Owners Reviews and Experiences


I have been using LS2 helmet with Mercury visors for more than 4 years and never been caught by cops for that reason.

Only problem with them is it's difficult to ride during night time with Mercury visors and they get scratched very easily.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Not really. Tinted visors are meant to be used only for broad daylight use, not for night riding purposes due to inherent risks they carry. One can use colored visors, but using it responsibly for ones own safety and others' is paramount.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Well, thanks for the info.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Yeah you get a message from rto that your vehicle is registered then you can take the bike home, number takes another 10-12 days of which also you will get to know by sms from rto then you can ride the bike without any worries of cops

Re: Yamaha FZ 25 Owners Reviews and Experiences


I don't think upgrading to steel braided lines or better calipers/pistons help here. Even better pads wont help much.

The reason being, the design and physics involved.
In case of front wheel, the suspension is pointing at 120 degrees or around. When you brake hard, brakes try hard to stop the rotation of the wheels. But the whole vehicle is in motion and tries to roll forward, even when you brake hard. During this time, vehicle tries to roll forward, however the front Heavy Duty suspension absorbs most of this rolling tension. Hence you dont have front wheels getting locked as much as rear does.
Check avenger and other cruisers. they have front forks set at more than 145 Degrees or more. Due to this, the rolling effect of the vehicle cannot be passed on to the suspension because of its angle, hence front tires get locked in those cruisers and people fall. Cruisers cant be ridden enthusiastically.

However coming to rear wheels, the concept is completely different. You just need pure braking power to stop the wheel. They dont get any cushioning from suspenstion when rolling. For effective rear brake, you need heavy weight on the rear wheel and a ton of contact patch from tire to try to keep rolling. And then you need normal pads to do the stopping duties.
You need more flatter tire for more braking at rear. but FZ25 has more rounded tires than FZ16.

Adding better pads and more piston calipers worsen the problem. why? You give more power to rear brake but your contact patch remains the same and weight remains the same. The new brake system stops the rear wheel but your vehicle keeps rolling. You endup fishtailing more.

You need weak brakes or ABS to do the stopping duties at rear. Or you can switch to a flatter 150 section tire, which should be a modest improvement. But FE takes a hit.
This is why most manufacturers give weak rear disks. Because, putting stronger brakes there worsens the problem. The older Drum brakes provide more braking than discs because of more contact area of brake shoes and their weak behavior. But people expect discs at rear because they think they are better. So, manufacturers are giving them what they ask even though its not a wise choice. check reviews on YouTube. Everyone is ready to complain, if there are no discs. Do you think, they understand the concepts?

Re: Yamaha FZ 25 Owners Reviews and Experiences

No. It's not a lie. I got my fz25 in the same manner. Did you get the sale certificate and insurance papers? If yes, you're fine.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Umm, I don't think that's the case. Newton was a great man and gave us so much of in-depth knowledge about the world of Physics. When a body in motion comes to stop, the whole weight gets transferred to the front of it. That's why you have a bigger disk at front, Multi piston if required. The rear disc is for slowing down the vehicle. Toyota Fortuner, in its previous avatar had rear drum brakes because for that ladder frame, the car was front heavy. The same concept is applied to the bikes. Cruisers have rear biased weight and bigger wheelbase to aid straight line stability. Disc setup is a better choice for braking, no matter if it's a Bajaj Platina or Ducati Panigale Superleggera 1299.
Steel braided lines is a definite improvement solution. Manufacturers know that they are better choice but that'll increase cost. Rubber hoses expand due to internal oil pressure. Steel braided lines keep those pressures intact and the effectiveness of lever-to-pad braking feel increases.
There is a general rule, accepted almost worldwide, that the braking should be done in a front:rear as 70:30.
As I said earlier, Newton was a great man. He helped me become a better rider with better braking control.

Re: Yamaha FZ 25 Owners Reviews and Experiences

I guess improving any breaking capabilities at the back will result in wheel lock up and fish tailing. Rear break is soft for a reason and dont think there will be a need to change if we use engine breaking along with front and rear. Rear break is for initial slowdown and front actually stops the movement and i guess FZ's rear does its job, unless anyone rides beyond the speed limit and without anticipation.

Re: Yamaha FZ 25 Owners Reviews and Experiences

Has anyone from Bangalore got the tappet issue resolved successfully? If so from which SC? I visited 2 showrooms, Laxmi International and Perfect riders, both of them failed to resolve the issue so far. A simple issue is turning out to me major annoyance due to lack of skilled/trained mechanics, not the best way forward for Yamaha.
