What is the tyre size of Triumph Street Triple 765?

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.

If you want a sportive bike choose between z900 and street triple... because Diavel looks bit like a cruise bikeAnd again if you come to choose between z900 and triumph then I suggest you choose between brands not bikes because both the bikes are best with no issues but when it comes to maintainence triumph donot usually have spare parts available at the service center.......... As my personal experience you have to wait for over 2-3 months for any kind of part as the spares come from U.K It took about 4 months for me to just get the triumph logos where as kawasaki has got better service than triumph
