From all reports, Suzuki shouldn't have sold the TM400 seeing as it is top of the list of worst bikes ever.
At the end of the day you can pick any manufacturer to bits as they all had good and bad bikes. Either side of the 81 490 Maico is the best example.
All manufacturers have stretched the truth as well regarding how close they were to the factory bikes. Maybe the reason why the European bikes were close to their own factory bikes was more the fact that they didn't throw as much money into R & D the way the jap's did.
E74,with regards to the 125 rd, i did the modern thing on mine( just a stocker though), great bike for sure but i think there is no substitute for 25 years of R&D.
