Some inputs from me about this...


Among many other factors, the ability of a tyre to hold the road rests primarily on the rubber compound and the tread pattern.


The compound on the ContiGos is relatively hard. When I say relatively, it is with respect to Indian roads which are generally quite rough. Such roads need a softer compound which will enable the tread to wrap itself around road undulations, dig into the rough part and enable grip. But with the ContiGos, the hard compound doesn't allow this to happen and as a result, the tread just glides over the surface without gripping it the way it should. An analogy is a soft foam mattress and a harder coir mattress.


The phenomenon of low grip is increased by the tread pattern on the ContiGos which is more suitable for the track (smooth, even and good quality surface) than the road (rough, undulating and poor surfaces).


One critical feature which is missing is a central groove, running all along the tyre, acting as a pump to throw water outwards and leaving a small dry contact patch. Again, the tread elements, whether in the central part of the tyre or towards the edges, are not connected in one endless pattern but are in individual segments. This type of a pattern does not allow water to exit the complete contact patch, whether straight and level or banked in a turn.

Thanks again, for the detailed explanation. Have to sit with her this weekend



my brother has been bugging me for one of those ABS modules for his Yammie...but i am not very confident on the product due to the lack of any kind of technical documentation. In my bro's case, I advised him to ride cautiously without ABS instead of riding overconfidently with a device which hasn't been systematically tested and proven.

In your case, since you are an experienced rider, you can go for it, just on a trial basis. But I'd suggest not to rely on it during critical situations.

Very good explanation...

@ icemang: pirelli sports demon are better than contigo in both dry and wet traction.

I have a few questions: I am thinking of replacing the tyres with :
110/70 - 17 Pirelli Sport Demon (is it tubeless?)
140/70 - 17 ContiGo (PSD not available, any other suggestions, have read MRF Zapper Q to be tube type and heavier than ContiGo?)
And is it fine with different make of tyres at both ends?

With reference to the discussion about tyres,am getting Dunlop Tuffgrip and ContiGo at the same price,Rs.2800. The central groove is not present in the ContiGo whereas there is ample groove on the TuffGrip.The walls of the ContiGo seem tapered and round,whereas the TG's come to an abrupt end. I'm also on the lookout for a rear tyre and am finding it a bit scary to fit a tube type Zapper Q as a tubeless.Is it safe enough?

I have heard of users using it w/o the tube. Even some dealers say it is ok to do so. You could use it tubeless for some days and if the air pressure leaks too much, fit the tube.

I have not tested the PSDs over the Contis so cannot corroborate that. Prima facie, looking at the tread depth and pattern, it does not seem too confidence-inspiring in the wet. On track, it would be awesome, though.

I don't think its a good idea to test a brand new zapper q.would rather go with Tuffgrip.

The tank itself is a bit wobbly - it causes a creaking ruckus like a 70's wreck.

tightening the bolts wudn't solve the problem.. trust me.. infact you'll end up with more shrill vibes... i'd suggest get soft rubber washers.. get the parts stripped from where you get the vibes.. mount the washers and then get it fixed again. this will solve the issue to some extent.

i used to get a lot of vibes from the front. figured out the space between the headlight assembly and the front top fairing was the culprint.
got a torn tube ( cycle tube) inserted a peice of it in between and all good since then..

@theironhorse99
I followed your steps and inserted soft washers between the tank and the fairing at the indicated points (green circles). I opened the front seat and tightened the bolts holding the tank under the seat. Next step was tightening the bolts holding the tank under the cowl near the fuel lid. Spent a significant part of my evening trying to fix the creaking tank, but today morning on my commute, the creaking sound was very much still present. :Frustrated:
One thing for sure, it's the mount-points for the tank which are vibrating and causing the noise. Got an off-day tomorrow, will take it to the ASC tomorrow to fix the noise and to get my clutch adjusted.

met another xbhpian yesterday.. was checking out his new cbr ... he's riding for leh-ladakh.
all the best buddy....
