It's already been a month since I started riding the CRF

I've done a lot of things, about 4-5 times, so I thought I'd write about it on my blog

I've donated two handlebars and a radiator during the past month, so I think I've been able to test it in a decent place lol

First impression: the engine has plenty of power

It holds up well even at super low speeds

The standard size sprocket is enough

It doesn't suddenly stop at low speeds like the WR, so it's very good

The thing I'm concerned about is the weight

I'm sure you've all noticed, but it's really heavy

I can't believe it weighs 140kg

133kg with the Serow Final

I tried removing the original CRF muffler and straddling it

The CRF's The stock muffler is 6.5kg

This is 133.5kg, so it should be the same as the Serow

But...

The CRF is overwhelmingly heavier...

Why?

Even though it's the same weight

Even if you actually try to reduce the weight, the effect is small

I removed the unnecessary parts, changed the sprocket to aluminum, replaced the muffler,

I compared the lifting of the Serow and CRF, and they are the same

But when you ride it, it's completely different

When it shakes on a rocky slope, it feels like it's being carried away all at once

My head is especially heavy

Does this expression make sense?

Even if the bike is heavy, if it's well-balanced, it doesn't feel heavy when you straddle it.

It's heavy to lift, though...

When you straddle the CRF, the tank cap is heavy and it feels like it's over 140kg.

I took it apart and noticed that the weight distribution is bad.

The engine is leaning forward quite a bit, probably for road use.

The engine is long vertically.

The head is heavy.

Off-road bike engines are almost always vertical.

The YZ leans toward the rider.

The Serow and foreign bikes have the computer and sensors installed under the seat.

The gas tank is also placed under the legs as much as possible.

The CRF has a lot of space under the seat.

Everything except the battery is installed inside the left shroud.

And it's in a high place.

The engine is already high and heavy.

Even though there's a radiator.

The location of the computers and the way the engine is installed make it 140kg. I think it makes the rider feel the weight of the bike more than the original.

I think the front and rear weight distribution is probably not right.

I understand that they had no choice but to cut costs and made it this way.

I'm grateful that they're selling it.

Well, I guess it's fine now that we know where to focus on making it lighter.

The trick to making the CRF lighter is to pay attention to the area around the handlebars.

If you're going to install handguards, choose something light.

Install ETC and other electrical parts under the seat as much as possible.

Make it the seat back rather than the tank back.

I thought the top bridge and stem should be made of aluminum, but the factory version is made of aluminum.

I want the tank to be made of poly and the meter stay and left shroud stay to be made of aluminum.

Development has started.

As for the muffler, we finished testing the second one the other day and are now on the third.

We test at least five of each model, so

A borrowed delta barrel. I even tested it with a full exhaust with a torque head

It's light and JMCA certified, but the power increase is small

I haven't run the third one yet, but it looks interesting

It's a muffler that will definitely reduce power‼︎ so please look forward to my impressions
