YBR125 150cc kit

[Bensis]

What about a 180cc kit? https://x-motor.odoo.com/shop/product/12000-xgz-0000-cylinder-kit-yamaha-ybr-180cc-20

I am running of buying that and a camshaft made for 150-180cc but is there anything else I need to do?

I gave two ybr 125 both have 150 kit and 16t front cog.

Recently back from 3000mile trip across Spain where the extra torque from 150 cc and a set of gears that exploit that made holds far easier and 60mph cruising easy enough, third gear acceleration in the midrange with these mods is very different....really !

150 kit was £45 16t cog £10 , no brainier. Both bikes have high profile trail tyres fitted which will also raise the gearing ever so slightly.

Put these bikes together for the trip with my son who is new to bikes. Iv messes with bikes for 40 years and I would say thus is the best value for money change Iv ever made to all the bikes Iv messed about with. Would recommend to all those who have respect for the solid, cheap, reliable ybr

Dependant on year, the YBR will probably be fuel injection. Mine is on a 2012 model.

The big bore kit also has 123cm3 on the barrel

I'm in my 40s and use mine as a daily bike (weather permitting) and have a Suzuki intruder 800 cruiser for special occasions and a car for bad weather.

Passed my bike test 17 years ago and the little YBR with the 150 kit on is a great little commute, always brings a smile filtering past all the stationary vehicles on weekdays.
