lonestar didn't make those frames.. the company that lonestar bought out did though.. it was called JP racing..
i've never heard of the leager LT250R chassis but i wouldnt; be surprised if they made them as well..
there is a company called HSD they was supposed to start making complete front frame sections for lt250s lt500s and banshees that were trx250R geometery that you could graft inot your lt or shee frame BUT.. the pland were drawn up.. they were advertised but none were ever actually produced... it's a shame i would have liked to have about 3 or 4 of them.. haha
