Beta High Comp Head vs RK Tek

[aj_mariner]

There’s no comparison. The Beta high compression head isn’t a night and day difference from the stock head. There’s still a bit of extra snap felt starting at the power band, but won’t pull the bike in the higher gears like the RK Tek head does. You don’t need to make any jetting changes, and can still smoothly cruise on road in-between trails. Beta reduced the squish band from 1.87mm to 1.38mm...but the dome is the same profile. The decreased squish is what increased the compression by roughly 10%.
If you bust or damage the stock head, then go for it. Otherwise...meh
