Vipin , in such a scenario that delicate plastic panels must be affixed to metal frame with steel screws or nuts , and vibration from motion is expected ; could they not have used rubber or silicone-rubber grommets and washers between the screws & the panels ? I have seen this is done in fixing Plexiglas windshields to stainless steel frames in front of bikes ... Surely this would have relieved the plastic from direct stress cracks ? I mean the engineers must have thought of some method of protecting the fairing etc which by the nature of the application , must be exposed to constant vibration and external use ?? Other than using the proper kind of plastics in the required thickness and strength ... Formula racing bikes and cars use plastic ( carbon fibre reinforced ) shells and parts too .... and never disintegrate just like that on the tracks even under abuse . Carbon fibre reinforced plastics are actually stronger than steel ... No way bike body panels just giving away by just hand tightening with screwdrivers possibly .

The problem is one of bad engineering and choice of material.If they had used traditional fiber glass instead of hard plastic, .....or even soft plastic instead of hard one, and given adequate support at stress areas,all this won't happen. Even with soft rubber washers on both side, the visor rattles badly and in course of time develops cracks,on mounting holes.

yeah thats not copied its like earlier HONDA used to give designs and engines to hero hero was more or like salesman but now when they get seprated earlier things will go like this only and in future hero will come up with there own designs and engines. rest we have to see what happens

Sir,
1. I agree on plexiglass windshield method to fix winshields on enticer/avenger etc etc, but Karizma styling is different.
2. Kinetic Marvel had metal screws concept but still cracking used to happen on this scooter. My Dad had Marvel and the biggest issue was vibes everywhere after 2 years of use. But rest of the bike was great, I still feel it's the best looking scooter on Indian roads.
3. Soft washers will not tend to hold the part rigidly and hence can induce vibes.
I hate these fairings concepts in first place, I hate lot of platics on bikes, they are more of asthetics and less of functional. A OEM has to play around styling,cost & maintain less vibes too. The solution is use of better materials that may not affect cost of the bike.
