EC300 Supermoto conversion

[motopsycho87]

Hopefully the gods of eBay will grant me a set of wheels, discs, tyres, spindles and spacers from a very common 17"er today (if not, another day very soon!!), in which this post will be my 'diary' for the process.

Stay tuned!

What is the benefit of the rm125 cdi?

[motopsycho87]

The benefit is that the EC300 CDI stopped working , though 125's generally rev higher and are timed to suit, so my bike may have super powers, won't know until I dyno it one day .

Anywho, I lost bidding on the wheels, so I bought another set of the same ones .

First hurdles will be the discs

Front disc -
EC300 - 260mm
GS500 - 310mm

Rear disc -
EC300 - 220mm
GS500 - 250mm

I'll start with the rear, in which I will either turn down the OD and see if there is enough meat left for braking, if not buy this cheeky little rascal

and turn out the center clearance!

[motopsycho87]

Bearings required (to fit 20mm axles)

Front wheel, 2x 20x42x13 (60042RS), (this is supposed to be 20x42x14, but good luck finding that bearing, the centre spacer will be the same length, just the outer spacers +1mm).

Rear wheel 2x 20x47x14 (60042RS)
Cush drive 1x 25x62x17 (I'll keep this the same and make the spacer to fit)

I've just done a similar conversion to my EC300, but with Aprilia RS125 wheels. I originally started off with Bandit 400 wheels but they were just too much work to fit. If I can work out how to post pics, there should be a photo of mine below!

My son Fredrik's 08 Ec300 Racing with 2010 (?) black plastic and stickers. He bought some seconhand 17" wheels locally. Luckily, they appear to be OEM GG wheels so the conversion was pretty straight forward. He uses BT090 tires.
The fron brake setup is a 320mm brake disk, 6-pot ISR caliper and Brembo radial master cylinder.
