We have a 44 tooth wheel sprocket for 8mm (T8F) chain that fits the Razor E300 scooter which is our item # SPR-844F.
To use this sprocket our 11 tooth motor sprocket for 8mm (T8F) chain would need to be installed on the motor which is our item # SPR-811D.
Since the Razor E300 scooter's original sprockets are for #25 chain when switching over to 8mm (T8F) sprockets the original #25 chain will need to be changed over to 8mm (T8F) chain.
For the Razor E300 scooter with an 11 tooth motor and 44 tooth wheel sprocket for 8mm (T8F) chain, the size of 8mm (T8F) chain that is needed is 78 links.
The SPR-844F and SPR-811D sprockets can be purchased on our 8mm Sprockets Page.
The 78 links of 8mm (T8F) chain can be purchased on our 8mm Chain Page.
