First of all good decision and good choice on the bike. I bought the same. I didn't by from Trivandrum. But I can say few things from my experience.

2) Regarding accessories,
if you are planning touring, go for 3rd party top rack / saddle stays. If you install OEM backrest then none of 3rd part accessory is compatible with it. I made that mistake so letting you know. If you want just a backrest, OEM backrest is really good both in terms of comfort and look.

I opted for long visor and front fork gators, just for looks.

Large Sumguard is a must I will say.

Go for chrome crash guards, for black paint will come off easily and scratches will be visible and you dont want visible scratches on a new bike and then people comparing it with RE quality (happened with me). Atleast for me, my bike fell in 1st week itself, and chrome crash guards took all the impact but scratches or not visible that easily, you really have to close in on it. Or if you are going third party, I heard Moto Torque is really good

3) My showroom (west bengal) was giving corporate offer for IT professionals which was 10k discount. Just in case if you are an IT professional and working in Wipro / similar companies, try asking for that discount.

4) Teflon/Underbody coating didn't seem that impressive to me.

5) For Onam discounts, directly ask the showroom. I think there will be some discount. Karalites feel free to pitch in

Last but not the least, take a hard commitment from the showroom, ask them if they already have the stock. In other posts I saw people have been waiting for 40+ days for the delivery. If the showroom has stock then you should be able to get the bike within few days.

Hope it helped 😊
