What size tires does the Sur-Ron Light Bee X take?

It runs 70/100-19. The exact fitment for your machine is on There is no placard. The size is moulded into the sidewall.

Can I fit a cheaper tire to a Sur-Ron Light Bee X?

Only at 70/100-19 or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.

Do I need the 2.50-19 marking?

Not legally. The 2.50-19 version can carry a different compound or an acoustic foam liner that the same tread pattern in the shops does not, so if the machine is quiet now and you fit the unmarked version, expect to notice.

Your own placard is the authority. You will find it on the there is no placard. The size is moulded into the sidewall. Where it disagrees with this page, it wins.

What changes on this machine

Front and rear take the same 70/100-19, which is unusual and genuinely convenient: one size to look up, and a worn rear can go on without matching a different front.

A 16 inch rear wheel is the most common modification made to this machine, and it changes the rolling diameter, the gearing and the ride height together. It is a different vehicle afterwards, and the figures here describe the standard one.

The original fitment is a CST knobbly. CST and Maxxis are the same company, Cheng Shin Rubber, which is worth knowing when you are comparing the two on a shelf.
