The Honda CRF150R / CRF150RB is a great motorcycle that gets Overlooked

The Honda CRF150R is a great motorcycle for the younger rider that maybe a little too large for an 85cc 2-Stroke bike. The CRF150R is also a great way to transmission from minibikes to full size 250F 4-Stroke bikes.

There is two ways to make the transmission minibikes to full size bikes. You can stay on 2-Strokes and ride super mini’s (big wheel) then transition 2-Stroke 125cc full size bike and then finally to a 4-Stroke 250F.

Now let’s say you are a larger rider you can turn to the CRF150R them the big wheel CRF150RB Expert (big wheel) and I feel the transmission to a 4-Stroke 250F may come faster and easier.

I know racers focus on the 2-Stroke Supermini’s, but I feel for some riders you are overlooking a great that for some rider’s the CRF150R may work out well.

The first thing you must make sure is the motor is in great condition. If you try get more power out of a tired motor in most cases, you end up with a mess. A bike that breaks down with major components failing and a lot of DNF’s. Remember most of will not have a Pro career so the time you spend riding and racing with you kid is priceless. Enjoy that time, remember if first must be fun.

First let’s talk Engine – Maintenance:

Kits contain all the needed parts to repair the bottom end and top end components. With a freshly rebuild motor you can expect easy starting with restored horsepower improved throttle response, with smooth trackable power.

Next now that we have more air we need to match it with additional fuel. By adding the correct Jet Kit we an improve performance. Allowing the additional air and fuel to pack the cylinder and create more power. 

Now that you are getting more air in to the motor. To make more horsepower we have to get the burnt exhaust gases out efficiently. Install a high Flow exhaust system
