I started learning japanese recently, and I looked back at the kanji I've learned, and I simply can't think of any kanji with an onyomi longer than 2 morae.
Is there really no kanji with an onyomi longer than 2 morae, and if so, why?

Recall that on-yomi are derived from the Chinese pronunciation of characters, which are (with few exceptions) monosyllabic. The basic structure of a syllable in Middle Chinese is as follows:
For instance, 關 (resp. 怪, 脚) is kwæn (resp. kwai, kjak) in Middle Chinese and has the kan-on クヮン (resp. クヮイ, キャク), but there are no syllables like kwain. Thus there is no way a trimoraic on-yomi would arise.
