11 tooth front sprocket

[volcano island trial]

I own 2014 Ossa explorer which I used it for difficult track trail riding. It has standard 10 tooth front sprocket. Do anybody know where I can get an 11 tooth front sprocket ?. Most mail order shop only stock 9 or 10 tooth. Or is it the same as some other bike brand ?

 

Thanks
