In the riders seat
If it was, Gav would only have to overbore 3mm to get competitive

Guys we have scales down at the kart track and our CB Twin was 105kg, loaded with fuel.
Not sure what the FXR/Loncin 150 is, but will see if we can weigh it at the next meeting.
MotoFXR's will rule the world!

Its harder to lose weight than gain horsepower.

had the scales out today.
RG150 frame = 14.5 kg. ( with a few extra coats of paint)
RG150 Swingarm = 5.5kg
KLR600 engine with carb = 48.6kg
NSR250 MC18 frame and swingarm together = 12.7kg (this has a seperate subframe unlike the rg)
My subframe (could be lightened for a bucket) = 5.8kg

125GP!!!
I swear its heavier!
Long Haired Yobbo
Yeah, I was surprised there isn't more difference.
I may try that one again just to make sure I got it right.

How do you make a swingarm that heavy?? Or does that include suspension link and shock??
Long Haired Yobbo
Nope, it may have had the bearings in it but nothing more.
They are all steel and Beefy, Bannana kinda bit on the right side and MASSIVE link bit between the two sides.
I think in trying to make it look like a sporty alloy one they wern't to worried about weight.
Mine may have had some water in if from sitting outside but it has been stored with almost 6 months to dry out...

How heavy's the RG's engine? 15-25? its not that heavy
Long Haired Yobbo
Pretty sure it would be over 20, maybe more like 30.
That is still pretty light.
I will check next time I have a complete one out.

My next project is a FXR150 Motor in a FZ Deltabox frame.
Frame, Rear shock and Swingarm 20kg, balanced on the bathroom scales.
( must remember to put those back before she gets home, aye)
The Fx150 motor was 27kg, but the cams and piston are out cos the motor is all blowed up.
Anyone interested in a thread on the build of the FZ/FXR bucket. Input from some of you fellas would be most helpful.

um, ok here's an idea. Why not put the fixed FXR engine back in the FXR? They seem to handle just fine & fairly light.
Don't you look at my accountant.
He's the only one I've got.

FZR has lots better running gear, 3LNs anyway though the earlier 2KRs are OK
