So anybody have a TZ or RS250 rolling chassis laying around?

I got an idea.

I know where 1 is that has a ninja 250 motor in it!! But only legal for formula 3 and up the way I read the book.... very trick bike tho

I want to build one with a 450 single for Trey.

[Danny Dominguez]

ahhh...there is a 450 on wera bbs..in the Honda section

What classes will it be competitive Walter ?.... Does an Aprilia RS250 Cup chassis work for the project ?

[Rich Wu]

Jim Hall had enough TZs to start a factory, but I think he has thinned the heard over the years. You might give him a call and see if he has anything left.

http://www.450gp.com/EN/kits.html ive been looking at these since Pikes is all-paved now.Thats about the only place I race my supermoto bike. And Ive also looked at others on the wera bbs. I haven't pulled the trigger cuz im worried about some details, mainly the swingarm angle that youre left to deal with when you lower the bike...it's pretty flat. An RS honda chassis may work well and an aprilia 250 sounds pretty good too. The resiliency of a chrome-moly frame sounds the best to me but I don't know if anyone makes a frame that will make a conversion possible. Remember the Jesse Davis 450..might ask him about some of the handling characteristics. I would think it's important to match the engine's power characteristics with the chassis that you select. Geoff Maloney at GP Tech has parts for conversions too. And a lot of knowledge. Keep us posted.

I've seen those but I really want a real GP chassis. The Honda RS250 is out because of the right side chain drive. I'm looking for a TZ250 now. Ill consider The Aprilia RS250 but I'm spooked a bit because I don't know much about them. The TZ would be my first choice.

I wanted to build one of these a decade ago, and I still do. The TZ is the best option for multiple engine fit. A roller is difficult to find. You'll want at least a '91 and more likely a '94 or later. I know where a complete Honda RS250 is, but it's more work to get it to work. The key is the center line of the swingarm pivot relative to countershaft sprocket, and the distance between the two. I haven't seen many Aprilia RS250s that have been converted, but remember those Cup bikes are lacking compared to full-on purpose-built GP bikes.

Rising Sun Cycles?
