Q. Is the ground clearance of 165 mm of the Triumph Street Triple troublesome on the Indian roads?

The street triple or street twin and even the Bonnie has a lower ground clearance and based on various forums it would scrape when you hit the speed breakers and with a pillion it is worse. Triumph does not mention.the GC but to what I enquired it should be between 140-150mm. However, the rear shocks can be adjusted for pre-loads and setting it up for a harder position (think level-2 of the pre load) it would circumvent the problem. You will have to careful during the entry to the speed breakers. But then you do not worry about scraping on most speed breakers. Other than ADV/scrambler types most of the SBKs have this issue of low Ground clearance. Once you adjust the preload of twins shocks and take care of slowing down you should be good. You cannot just go over the speed breakers like you do on RE’s or other Indian bikes.

Using Nnja300 for a couple of months now. It has a much lower 140mm clearance. I must say, most bumps are no problem at all, just some poorly made speed bumps need a little care. just walk-roll over the "dangerous" looking bumps and you will be all right.
