You can explore the southern coastline of India which has some spectacular beaches to offer. You can start from Pune heading towards Malvan/Tarkarli (which in Maharashtra's inhouse Andamans 😉 as in it has some decent under water diving sites to offer). Further proceed to goa and witness the enchanting Bhogwe beach on your way. Proceeding further to ratnagiri, then managalore/udupi you can enter Kerala. The list of amazing beaches and hill stations is endless! You can DM me if you wish to get some more details about where to go in Kerala 😊 Happy tripping!
As Poorvi explained, the beaches of Maharashtra are good. But afyer visiting a lot of time, I'd recommend you to stay away From Malvan and Tarkarli, due to a lot of tourists, these beaches are not as clean as they used to be. There are many other places like Vengurla, Harnai in Dapoli, Shrivardhan. Just open Google maps and zoom in and choose any one.
Being a rider myself who has visited Konkan almost every year or my life, I know what a rider wants after a long travel, Relaxation and adventure after it.
You may also visited Narsobawadi in Kolhapur if sitting on river banks ans attaining peace is your hobby. It's a much underrated destination.
If you want to know anything more about Maharashtra message me directly, I'll be happy to help.
You can go to Wai, Mahabaleshwar instead of beaches as beaches aren't good ideas in summer. Wai is peaceful and the temperature is good. Also, Tarkarli is a very good place for water sports in winter. The water is clean and clear but would not recommend bike ride. It takes around 10 hours as it's near Goa. Also you can check out some summer night treks.
I doubt the lockdown will end any soon but oh well. All options mentioned above are great, but my favorite choice would be Mahabaleshwar, Kerala and also Malvan/Tarkarli. Though these locations should be visited separately unless you want a big trip. I would also recommend getting a big travel back pack like this https://cleverwander.com/p/best-tactical-backpack/ for this trip.
