TRX250R hybrid trx450

[J51S]

I was told to post in this section to get some better feedback. My current quad is a 400ex hybrid with a trx450r motor. After racing it a lot I found out how weak the steel is on the frame its got a few cracks.

So I will finish the season off with it repaired but I picked this frame up for next year. 87 R frame professionally modified to accept the trx450r motor. I had to buy it! I always felt most comfortable on my R so this will be a perfect swap over. Here's a pic when I first got it. Over the winder its getting Full Gusset kit +PC.

And experimenting with 450R swinger geometry.

This shows a 400ex length shock with 05 450R length swinger. 05 front linkage, 06 mx link.

Please don't take this the wrong way but is the 400ex better in anyway than a stock TRX450r chassis. I can understand 450r/250r hybrid but just kinda curious. I have a 400ex chassis and was going to sell it for a 450r chassis because it already had a rad mounts etc.

are those 250r rear plastics? if so how did you get them to line straight up with the front 400ex plastics?

If I had to pick between the 400 or 450 frame I would just go with the 450, its already done and a bit stronger.

The 400ex frame is just very weak. If your going to use one fully gusset it and get a good suspension setup. And 450/400 frames both need lowered sub-frame modification and mx link imo to be optimal for mx.

Yea they are 400 ones were out of stock and I had a race coming up. I made em work. Cut a lot of the plastic away to get the seat to fit in the and sit ok.

Mounted the motor to check clearance's for tank, kick lever, carb etc.

Another shot with the motor

And got all the gussets in place for the welder.

Another angle on the gussets

Kit didn't come with the shock brace so I had to make my own.

Slowly coming along

Looks good I like the carbon shrouds and the blue frame.
