Thank you, I hope I can be help ful.
1 - Handle : You have two choices Clip -On or Short Size Handle but in both cases remeber what you are gaining and what you are losing this is very important, because if you put these handle and remove original, you seating Style would Become aggressive and more leaned over the fuel Tank and you will get much more load to front giving you more control over the bike with very agressive manuverablity (jisay hum yahan per Cuttain MArna kehtay hain),
Now WHAT you will lose : THE most important featue : COMFORT because you are in aggressive mode now and half of you chest wieght is on you shoulder just like heavy bikes and you will be tired or become muscular from shoulder very soon :D, now you know why Heavy Bike riders are always Body Builders ...
2 - FAT TYRE :
I have heard Mixed reviews from Riders as I have'nt done it with my own bike, but people who added Tyre maximum to 100/100/18 the experiment went super well,, but those rider who went beyond 100/110 have very bad experience and according to them bike loses its Thrill completely, even on 110/100 according to SK bike has decreased almost to 5~10%
Solution For Fat Tyre Bad performance : Last day I called bilal autos to ask about Duct Tape used on silencers for Hidalgo, and discusion went long and Hafis gee (the main mechnic there) told me that if you dont want to lose performance and want to enhance the grip and put a fat tyre, then switch to 17 RIM instead of 18 and you will see the magic I hope thats what you also wanted to hear.
3 -Alloy: NOT a good Idea Simple. Bike becomes a Petrol Drinking CD 70
Hope it helps.
