Has anyone ever put a dr650 engine in a lighter bike?

Recommended Posts

Took a friends DRZ400 for a spin recently. I was looking at side by side with my 650 thinking that a 650 engine in the 400 chassis "might" make for an interesting and lighter bike. I'm in love with the torque of the big engine and think it'd be great in a lighter chassis. Anyone ever tried it? On a DRZ or anything else?

And yeah I'm a tinkerer who does stuff like this a lot.... even if it doesn't really make all that much sense. :thumbsup:

Most of the weight difference between the 400 and 650 is in the motor.

Yeah I sort of figured that after looking at them next to each other. The chassis are pretty similarly designed. What about a motocross bike?

I've been intrigued with what Drjoe did; cutting off his subframe, building mounts and using a drz400e subframe. Said it was about 8 lbs of weight saved. A couple of pounds with plastic tank, 10 lbs off the exhaust, 6lbs off battery and then 8 off the subframe. It adds up..

I have a lightweight avenger wiith a tt250 motor that I was having trouble with, and I had a dr650 andd I thought I would try to put it in the avenger,but after pulling the Dr motor I backed off because of the weight 105lbs sizewise it probably would have fit but I just didn,t want to deal with the weight,

How about just making the 400 a bigger bike? Right now there's a 470 kit out there that will definitely put a smile on anyones face. Talk to Eddie on the jetting or DRZ400 forum for details.

Is there a detailed write-up of this? I'm interested!!
