An unlucky incident or Do I need a tyre change?

So something happened tonight while riding home from work and it has kept me up until almost 1 am now so I decided to seek advice from more knowledgeable folks.

So i ride a Yamaha R15S. Owned since December 2016. I have clocked 18k+ kms on it. The tyres are still the ones that it came with. Year of tyre manufacture is 2017. Both front and rear tyres have had a couple or so punctures that have been repaired well.
Both tyres have worn more from the middle but it isn't too extreme. Its just that the original shape is now gone and its slightly squarish in the middle.
Both tyres have a decent tread depth remaining, i reckon at this rate should last this year.
I commute 40 kms a day, 6 days a week and fewer kms on Sundays. All of it on mixed road conditions.

Now tonight on my way back home, i took a corner at around 40-50kmph. I came in faster, braked at the start, let go of the brake and pushed the left handle bar and leaned the bike over.

*** In the middle of that corner the front tyre started to slide ***

Luckily, I had kept a loose grip on the handlebars and handlebars wobbled a bit but the bike corrected itself and i was able to make it out of that corner.
I don't think I had leaned the bike over too much, like say - beyond 45 degrees. I definitely did not apply the front brake when leaned over. There wasn't any gravel on the road either. Might be a layer of dirt, but I couldn't see a patch of it. The road did feel shiny under the street light but couldn't see a water or oil patch either. The front tyre shoulder also looks good with deep treads. I am as of now not sure of cupping, will check tomorrow morning.
I had taken the same corner at about the same speed- or slightly less maybe - yesterday with no problems

Now I am not sure whether it was something I did wrong, something on the road that caused that sliding or whether the tyres have hardened enough to not provide good grip even from the good looking shoulder region. Maybe I did lean it over too much and didn't realize it? Maybe there was something on the road i didn't see? Sleep eludes me tonight.

Should i go ahead and replace both tyres? Thoughts appreciated.

Re: An unlucky incident or Do I need a tyre change?

From my experience of horent and stock mrf tyres, I would like to suggest two checks before replacing the new ones. Firstly check that the tyres are considerably undergone wear and tear. Secondly check for the conset bearing stuff.

Re: An unlucky incident or Do I need a tyre change?

I don't know if you know this, but after you let go off the brake and before you lean over you should slightly crack open the throttle and apply a slight gradual throttle through the remainder of the corner. This ensures that the rear is loaded more than the front wheel and offers better traction. I read this in a book some years ago, but don't remember now.

Re: An unlucky incident or Do I need a tyre change?

Thanks. Sounds like solid advice. I thought you were supposed to keep a steady throttle going in a corner and start rolling on it after midway through the curve. Will try rolling on a bit at the entry but I fear too much will cause the rear to slide

Re: An unlucky incident or Do I need a tyre change?

SLIGHTLY!!! When you brake the front shocks get the entire load making it heavy. Once the braking is done you gradually increase the throttle transferring the weight to the rear. Too much throttle you'll lose the rear.

Re: Tyres

Any good upgrades over the stock zapper fs and zapper y for a Honda shine sp? Now that monsoon has started, the lack of grip is severely felt with this combination.

Would an upsize over the stock 80-100/18 to 100 section be feasible?

For the rear in stock size mrf mogrip, ceat milaze, ceat zoom xl, ceat grip are the alternatives. Are any of this significant upgrade over the stock zapper y?

Similarly for the front ceat zoom plus f or mrf fq are available. Not sure if these are better that fs.

Re: Tyres

go for mrf fx1 90/90 for front if available,
mrf mogrip for rear

Re: Tyres

Apollo Alpha H1.

The much awaited first ever W rated motorcycle tyre by an Indian manufacturer.
Apollo has used latest technology in developing these tyres.
These are made to compete directly with likes of Pirelli and Metzeler specifically Metzeler m7.
These are suitable for Duke 390, Duke 200, Rc390, Bajaj Dominar, Tvs apache rr310, Mahindra Mojo and other bikes with similar sizes.
Life as claimed by company is 50 percent more then Metzeler m7 with superior grip and 2 years unconditional warranty which means even the accidental damage is also covered till there 50 percent tread remains(do confirm this with your dealer).

A little history about this, we (our dominar group) was earlier invited by Apollo tyre in the month of April 2018 to show us new high speed high quality tyre they are about to launch in near future. They contacted me through my close friend who is the Dealer of Apollo in Delhi so we end up arranging the event with coordination with our Bajaj ride coordinator. In that event they didn't actually showed us the tyre but their team from Chennai was there and they spoke with us regarding what we need from a tyre, and showed us with help of slides what type of thing they are set to launch and what technology is used , but due to request by team apollo we did not share any pics or videos of that event.

Now coming back to the tyre the official launch is set for July 2018 in pataaya, but the tyre is now available for retail in some local markets, and as soon as it landed here in Delhi my Dealer friend wanted my bike to be the first to get these, though i have only done half the life of my stock tyres.
So, my Bajaj Dominar is practically ended up being the first ever Bajaj Dominar to be fitted with these.
Main feature of these tyres is the special construction using 0 degree steel belted technology, which means there would be no dynamic heat expansion like normal radials and other nylon/fabric tyres.
And this being w rated which is 270kmph speed rated is the first ever Indian tyre in this zone. Now the other benefits of being 0 degree steel belted radial is a lighter and stronger carcass, and with zero dynamic heat expansion the side wall would not crack , which is the issue most commonly faced with Mrf revz c1 and fc1.

As per Weight comparison the outgoing mrf revz c1 rear was close to 6.5kg and this Alpha h1 rear is 5.5kg, a full 1 kg lighter.

Now i have been using these tyres locally since last five day(got them fitted last Friday).
So here is my two cents.

Overall grip is leech like and is a big time improvement over the stock tyres.
Did the break test yesterday there is big time improvement, on the lean the tyre sticks well to the road and respond swiftly to body movement, unlike mrf it gives confidence when the bike is leaning.
Front end on the other hand has become bit heavy and sticks well to road it now needs bit more effort and awareness but is confidence inspiring.
It is like when the power steering of a car which gets heavy with speed to provide stability.

I am not allowed to disclose the price/deal i got.

Here is the contact details of my dealer friend , you can contact him for price and other inquiries , he can also ship to other states.

Re: Tyres


will these be coming in 150/70 or 160/70 ???? any idea on that ....

Re: Tyres

110/70 and 150/60 are currently the only 2 sizes as of now. As per company reps they will be launching new range in future.

Re: Tyres

sounds good. i have about 6 month before i change the michelin for my CBR and 150/70 would be great if it comes up... thanks for updating about this tyre.
will keep this in mind before i hit another tyre change..

Re: Tyres - RX135

Hi All,

I'm am looking to make changes to the RX135 5-speed footwear.

I know that MRF zapper FS/FV are recommended for front (2.75/18) but I'm interesting in the Moto-D series.

Would there be any demerits in running

• 2.75 x 18 - Front - MotoD
• 3.25 x 16 - Back - MotoD (Alternatively 3.00 x 16 if 3.25 is unavailable)
• Understood that 16" reduces handling but I'm used to it since years

Currently this is what I have going on :

• RX135 4-Speed
  
  • Recommended : 2.50 x 18 Front & 2.75 x 18 Rear
    
  • Current setup : 2.75 x 18 Front (Michelin M45) & 3.25 x 18 Rear (Yezdi)
  
  
• RX135 5-Speed :
  • Recommended : 2.75 x 18 Front & 3.00 x 18 Rear
  • Current setup : 2.75 x 18 Front (Stock) & 3.25 x 18 Rear (Yezdi)

Thanks in advance
A
p.s. Open to Michellin Sirac as well that M45 is ancient and still doing great.

Do scooter tyres wear out faster than motorcycle tyres?

Friends,

I am a newbie, an investor cum security analyst also covering 2 wheeler tyres.

I was looking to get a basic query answered by experts here. As you know over the past few years scooter sales have risen much faster than motorcyles and so have scooter tyres. Now it stands to reason that assume that scooter tyres wear out faster than motorcycle tyres, because there are probably say 2 rotations of a Honda Activa tyre to cover the same distance as say a Bajaj Pulsar tyre, thus wearing out the tyre faster.

Industry folks however say that they see motorcycle tyres replacement demand to be higher than scooter because the motorcycle tyres are subject much bigger abuse. They are yet to see scooter replacement kick in in a big way

Which one of the two is correct in your opinion?

Thank you for your time.

Re: Do scooter tyres wear out faster than motorcycle tyres?

whichever scooter may get launch , total bike will be always higher than scooters . Anyway tyre life depends upon the rubber used , it can be soft compound (low life) medium or hard (high life but less grip)

so scooter have a low tyre life due to more rotations per kilometers & soft compound

Re: Do scooter tyres wear out faster than motorcycle tyres?

This because of the usage patterns.
A lot of scooters are just errand machines for the ladies and students with very less mileage per month-motorcycles are more likely to be used as workhorses accumulating mileage very fast-a friend has a courier service and owns 15 Bajaj CT100's-AVERAGE running of each bike is close to 5000kms a month-hence tyres are replaced every 5-6 months or even earlier sometimes.
