@xenologik. Thanks so much for the help...im going to try and stiffen up the suspension and then see what happens. Does anyone else with an rtr and michelin m45's have this problem?

Could anyone tell me how much the irc tyres cost...??
coz i found a dealer selling irc tyres here in mysore and he quotes 2.5k for the tyre size 130/70/17"

1.6 K

but it is sold for 2.4 to 2.6K at most places.

in mumbai it costs 3600

Guys, I have a few queries.

What is the difference between 17" and 18" tyres? Some bikes have 17" while others have 18" tyres. What difference does it make in terms of handling, pickup, mileage, etc.

Can we fit 18" tyres on a bike meant for 17" tyres by changing the rims and vice-versa?

thankyou..! but i bought the irc 130/70/17" tyre for 2.4k..!

sounds like a pretty good diwali gift for my bike....!!

It depends on the size also i guess.
I got 110/80 T\L for2.4
I think u got a good deal

Okay, let me try.
The first obvious difference is the wheel diameter. Wheel = Rim/Alloy + Tyre

Though the handling, pickup and mileage do depend on many more factors than wheel size, considering them to be constant we can say the following in a very generic way:

handling - smaller wheels have better flick-ability but larger wheels can take bad roads better.

pickup - smaller wheels make for quicker rotation and better pickup. larger wheels make for more relaxed running and higher speed

mileage - larger wheels deliver better mileage


You can, if you change the rim/alloys. You cannot get an 18" tyre onto a 17" alloy or vice versa.

Even when changing the rims, if switching from 17" to 18" then consider the clearances in the swing arm, under the seat and the mud guard.

i guess the wheel dia can be worked upon. a higher profile low width or low profile wider tyre can give u comparable overall diameters betn 17" and 18" provided we keep rim width same.

Thanks a lot for the info guys!

VYDE for 180 UG3

I am owing 180 UG3.thinking of tyre change.i wanted to ask if the zapper vyde is a direct fit onto ma bike without altering/removing chain guard,swing arm.because i dont want the tyre to touch the chain guard.will it fit properly?

Maverick thanks for the suggestion, it worked! The only time it rubs now is when the bike hits a hump or a bump really hard...that i can live with. Me and my friend drove/rode pillion alternatively up to Puttaparthy this weekend and we didnt have a single problem .

Riding height

BTW instead of modifying the anchor points why not just use a set of shockabsorbers with slightly more stroke? ( assuming that they are available).

When we are on the subject of the shock absorber anchor points and the swinging arm. I would like to point some anomalies I have noticed.

All of the foreign bikes I have seen and about (90% approx.) of the indian bikes have the swinging arm and the shockabsorber anchor points or suspension clamps as mentioned ( shown in the orignal post ) are perfectly aligned. But in the 10% ( including some Honda ), the anchor point welded to the swinging arm is out of alignment. The anchor point is welded partially outside the swinging arm on one side and partially inside the swinging arm on the other side.

This kind of work indicates that the bike body and the swinging arms are not in line. Some measurement is not correct during the design stage or substandard manufacturing is to be suspected.

You could check for yourselves .

See the Attached pictures. Click the images to get a bigger picture.
TVS Fiero is the only one in the picture that has the Shockabsorber Hangers welded correctly and are aligned properly.
This anomaly is only on the Square section Swinging arms employed.

Thorns on tyres

The tyre molds have a large number of holes through which steam enters the mold for baking the tyre during manufacturing / re-threading process. The " Thorny things " are rubber entering these steam holes during the process.

no need for me to do this now , see above
