Nothings worse then a flat tire to ruin your day , worry no more with these Herculean tubes.. A must for those mini motocross bikes without a rim lock.

TUBESSSS

Good tube for the price have had on my bike for over a year and was at the track and must have pinched it, and caused a flat. But for $10 a tube i got my moneys worth easy to install. If you're worried about flats just go with the ultra heavy duty tube. If not run the heavy duty they will not disappoint.

STI Tube - Average

I measured these against the Kenda Tuff Tube and IRC Heavy Duty, These are by far the the thinnest followed by IRC, with Kenda almost 1/3 Thicker. I can't say if they are better material or construction though. Good price.

Heavy duty tube

The tube was quite durable. Except for when I inflated my front wheel, the tube had blown a hole. No worries, I just patched it up and secured it with heavy duty tape.

Tough tube

Installs like any other tube. Thickness add a little complication. Survived my mangled attempts to install the tires. This plus 8oz slime continues to hold air, which is all I can ask.

Serious rubber

This thing is built to play. Nice and thick tube goes right in, and and as always motosport.com did an awesome job with customer service. I most definitely will order again and again for all my riding needs.

It's a tube soooo....

It's a tube, so not sure what to say? It holds air, installed easily without pinching. Seemed to be of good quality material. Only one ride on it, but no problems with it, I am sure it will last to my next tire change. I always throw a new tube in when I do tire changes. Better safe then sorry!

STI HD tubes in kx65

I have 10 dirtbikes that cover my family of 7. I change tires, lots of tires. Little bikes are the worst so any product that can limit my minibike tire changes is so worth it. These tubes are super heavy duty and no problem to install. We ride alot in rocky terrain and also the adults use the minibikes as pitbikes so they get a workout. I highly suggest these tubes, great value also.

Good inner tube at great price

It's thick. It's black. It's rubber and it's round. It serves its purpose and does well doing so.

Good product W/one flaw.

The valve stem caps they supply does not remove valve stem. Keep going back to the metal ones. It is a waste of time if you have a flat and don't have a metal one with you.

I'm terrible at tires!

...but this is definitely better and stronger than stock. Maybe an oz or two heavier, but I'm not paid to ride. Give me durability any day

Q: I need the 3.00 by 12 inner tube! is it under a different #?

A: As far as I can tell, there's no 3.00x12 available for this tube. You could try a 2.50x12 and run a little higher pressure, but there's a good chance that'll shorten the tube's life. I'd suggest checking other tubes to see if they fit.

A: The STI Heavy Duty Tube comes in a 80/100-21 size for the front which will fit that 2.75x21. For the rear they make a 110-120/100-18 fitment that will work for the rear tire.
Chirs
4 months 9 days ago Location: SE Wisco
A: If you select your bike, the corresponding tubes should pop up in the drop down menu.

For a 2.75x21, you can use any tube from 2.50-3.00 with varying pressure.

For a 120/80x18, you want at least a 4.00 tube, but preferable a 4.50 or a 5.00. a 120 rim is about 4.75 inches wide, so you want a tube close to the same width.

A: You will want to get a 3.50x8 tube for that tire. The 2.50x10 are used on the newer 50s with 10” wheels. You can find the 3.50x8 tubes in the OEM section under the Honda Z50.
