Check the brake pads? And also the master cylinder for leaks.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

The first thing I checked when I encountered play in my braking are the disc pad and the brake fluid. Checked with svc guys and they said its all good. Not sure about cleaning and all but they have tightened the brakes in front of me by removing bubbles in it. Also, let me confirm you that bite was never an issue, its just that the lever has far greater play than it usually does.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Hi Vinay,
Here you go.
Need to check these:
1. Check the brake pads. If worn replace it.
2. Generally brake fluid must be low if the play is increased. Top up. It happened with me exactly after 8000 kms.
3. If the brake pad is not worn ( I believe 8000 - 10000 km is the average life of brake pads), then open it clean it, rub on rough surface and put it back. After 50 km of run you will start feeling the bite. Also top up the brake fluid in this case too.

Check this and let us know.

Guys, sorry for the mentions, we've got 2 people including me with this query and a possible problem, see if you have any suggestions. Thanks much in Advance.

Regards.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Yeah I have been observing it too. Free play of the brake increases over period of time. Have taken it up to service center guys and all they do is remove air bubbles from the braking system. After this brake gives a wooden feeling. Don't know how this can be fixed.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Alright good fellas, need some advice here.

Bike - R15S (2016)
ODO - ~8000 KMs

Since a week or so, I've been observing that after riding the bike for say 20-30 KMs with good usage of front disc brake, I find the front brake lever free 'play' more than usual. (Let's say double for the ease)

The first time I observed that, I parked the bike, waited for it to cool down and then pressed the front brake lever 5-6 times quick, which then reduced the free play to original. I didn't face this for 3 days then. However today again the same thing happened while I was coming to office. I realized the free play suddenly is more than usual. Please note, even if the free play is more, the brake bite and feedback remains as good as usual, I just have to pull the lever more now.

I checked the front brake fluid by keeping the bike straight, its somewhere between the middle and lower end. And I've been noticing a slight grinding noise while applying front disc brake since some time, which I can feel on the handles too(its kinda of unusual to me, since it wasn't there before).

Any suggestions on this are appreciated. I have my 5th service day after tomorrow, so I can take it up with them accordingly.

Regards.

The R15S is also lighter by a few KGs(3 or 4) than V2.0, so there its balanced. Rest they are exactly the same, except the seat.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Both engines are same, only tuning is slightly different. In r15s the tuning is done to get more power at lower end of rpm. However its not noticeable.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Hello all,

Few clarifications needed between R15 V2 and R15S

Comparing R15 V2 and R15S, I see there is a drop in cc (149 in R15S vs 149.8 in R15 V2)and in ps (16.58 in S and 17 in V2). I would like to know, from your riding experience, if there is a considerable difference in power between the V2 and S. Also I read somewhere that V2 has an O2 sensor, does R15S also have it? And the spec sheet (as seen in yamaha website) of V2 says the engine has 4 valves but it's not mentioned in R15S spec sheet page. Can someone confirm that R15S also has 4 valves?

All in all, in real world performance, is there something that's missing in R15S compared to R15 V2?

Thanks and cheers.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

For the guys who are planning to increase the handlebar height for comfortable touring.

The fork dia of R15 is 39mm, just 2mm bigger than Pulsar 200s, after going through the videos of Gixxer sf owners using the clip ons ons of R15 which is 2mm lesser than Gixxers(41mm).
Same way R15 could use the clipons of NS/RS 200.


Its explained in this video



Cheers.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

I too got pains initially on the wrist and even now but no back pains ever. The riding position makes the spine to lean at an angle so the shocks wont be transferred to the spine. I cant say wrist pain rather its a soreness and its due to the angle of the handle bar which causes uneven pressure across the palm. 30 secs of rubbing the palm in the breaks will make it back to normal. I would rather have the palm soreness for few secs than suffering with back pain for the whole day. BTW bike has completed 24K kms in 14 months.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences




RS200 has 37mm forks, r15 has 41mm I think, since you are trying to get it done fabricated, see if anything canbe done on RS200 handle bars to so that it suits R15.

RS200 handlebar is alloy.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

My idea is to get hold of or fabricate slightly taller clip-ons with current dimensions, without even touching the fork alignment.
E.g. the RS200 ones. Those buggers are really high.

No idea buddy. My manual doesn't even mention the fork size, just says Telescopic front.
No clue on the R3 ones either.

Regards.

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

R3 and r15 has 41 mm forks right?
If yes, it must be a direct fit.




Sorry if am Wrong!

Re: Yamaha YZF- R15 S Owners Reviews and Experiences

Always happy to Help.
Do let me know if you find a suitable way to get clip-ons a bit higher, without hampering the handling characteristics of the bike. I too would like that.
Ride safe Brother.
