Wet weather traction improvement groovesDid you face any thing unusual in riding on cemented roads ??
I am not comfortable on cemented roads with round type tyres.
It glides left to right because of small lines / grooves in cement top finish.
I had this experience earlier in Rajasthan on Activa with MRF Zapper Tyre fitted at rear and front.
Sample image of grooves :

These groves can be at parallel distance as lines may be some machine is used for such finish..
Anyone faced this problem earlier on a 2 wheeler ?
This form of pavement groove is installed on road surfaces to help reduce hydroplaning and skidding on wet road surfaces. Often you will encounter these grooved sections on roads that have a history of many wet weather crashes. Although grooved concrete surfaces seem to be more common, this road surface technique also is used on asphalt. Wet weather grooves are applied in two ways: perpendicular to the flow of traffic or parallel. Both function similarly to the rain grooves on your tires — they create channels to remove water from the tire/road contact area. The depth of the rain grooves and spacing between grooves are typically uniform.
The effects of perpendicular rain grooves on your motorcycle’s handling are minimal. Think of it being like the rumble strips along the edge of many roads, but smaller. Parallel rain grooves can have a more pronounced effect on handling; it feels like the road surface wants to influence the steering of the motorcycle. Unfortunately parallel rain grooves are less expensive and quicker to install on new road surfaces, which makes them a more widely used option.
Parallel grooves affect handling but are easier to make as they attach the mechanism to create grooves at the back of paver machine. Since paver machines travel along the road direction so making parallel grooves is fast and easy. Making perpendicular grooves requires more effort.
