This 150cc big bore kit added a nice little bump in power to my small trail bike, it’s not a game changer but for the price it gives a subtle yet noticeable improvement.
Rudy –
This big bore kit was a total waste of money – I couldn’t even finish installing it before giving up. Don’t bother with this thing.
Rocco –
The 150cc big bore kit woke up my TTR125 engine – more power everywhere and way more fun to ride now. BBR’s kit and customer service were fantastic.

The 150cc big bore kit from BBR boosted my TTR125’s power and made the throttle way more responsive. I’m really happy with how much faster my bike feels now.

This big bore kit has great performance upgrades like the aluminum cylinder and camshaft but the shipping took forever.

I bought the 150cc big bore kit to make my ttr125 faster but the instructions were confusing and it took forever to install this thing. Overall it sounds mean now and adds excitement to an aging dirtbike but didn’t instantly win me races so I’d say it was an alright upgrade and made the bike more fun.
