Upswept rear tail hoop help
« on: June 04, 2014, 03:52:20 PM »
Gents, I'm getting ready to order an upswept rear tail hoop http://www.dimecitycycles.com/vintage-cafe-racer-caferacer-chassis-frame-parts-dcc-originals-rear-steel-seat-hoop-section-tail-dcc-350450cafetail.html and brat seat http://www.dimecitycycles.com/brown-dcc-originals-upswept-leather-wrapped-brat-style-motorcycle-seat.html from Dime City and, because I'm at work and forgot to check before I left, I don't know the frame tube diameter.  Does anyone know if it's 1" or ⅞" and has anyone done this before? I assume also I should order the small CC hoop. 

Thanks
Rob

The frame tube back there is 7/8", be careful tho...

If you cut the end of the frame off and weld that on with a flat seat on top, you are losing several inches of clearance for rear suspension travel. The tire may hit the bottom of your new seat under full compression.   

Double check what you are doing by removing one shock ( to make it easy to compress the rear end)  to see your max travel and shock stop position.

A owner brought by his brat seat TX500 awhile back and the bottom of his seat was scarred by the tire. Could be very dangerous at speed cresting a hill when making unexpected contact. He had oversize tires, so check your clearance with what you will be using.  also- Just adding longer shocks is not a fix either, it screws up the geometry and will result in a squirrely steering. just 'sayin  :D

Good advice, Thanks.  I'm keeping the rear fender underneath, so all should be well.  All I've done was shorten and section it to retain the original line.  I'm going to tracker style tires, but not larger, just slightly wider. As far as shocks go, i am going to replace the originals with stock length (just all black), but i keep forgetting to measure them eye-to-eye.
