Kawasaki Estrella エストレヤ RSx360 (1996) Cafe Racer vs. home made engine parts

Автокөліктер мен көлік құралдары

In 2015 I had chosen to make the Kawasaki Estrella - also known as BJ250, or little W650 - a bit faster and slightly more sporty. A little bit of wind from the front and it would hardly reach 100 kmph in original condition. What a pitty for bike I really like for its beautifully clean engine an its overall simplicity. But when I started the project quite quickly I had to realise that there are hardly any custom parts on the market and basically nothing for a „hotter“ engine.
In the end it took a couple of hundred hours to fit the engine with a home-made titanium con-rod (small end Pin 18 instead of 16 mm), a customised piston and cam shafts which went through many hands to get developed. Bore is 79.2 mm now which results in 360 cc given the stock stroke of 73 mm. The power output of the bike has almost doubled relative to stock which is why secondary transmission is now 18/35 instead of 15/38.
After all, it makes a lot of fun to ride this little 135 kg / 35 HP fun bike. And I think it looks quite good considerring that only smaller modifications were made to the base of it.
Thanks for your positive comments.

    Fantastic work Seigfried , I've been looking for some tuning ideas a 250TR engine and couldn't find any at all apart from noisy mufflers . You've certainly pushed it to the limit with superb ingenuity. Great job 👏

    I think most people (me included) follow you mostly for the 2 stroke Jawa, and don't care about the 4 strokes. But that's too bad, because this really shows off your amazing still as an engineer. Especially when you made that custom conrod i was absolutely amazed!

    @@Quiet.Light.Engineering Yeah, and i live in Japan. The Estrella being a 250cc bike doesn't need to pass a two-yearly inspection. The W does, and each time it costs 80,000 yen (Works out as being about 3000 yen (about 30 US dollars a month) a month just to keeo it registered. My W is also a bit of a mess, having chopped and changed a lot of parts. Nevertheless! It is a glorious W.And being a 650 has a kick-start! Which the Estrella doesn't. The W is way more powerful and feels like a Concorde compared to the Esty which is a Dc3. But the Esty is gorgeous as is, and being largely untouched, would come up like a gem. Also, touring over here is either boring freeway or low speed back roads. So 40-60kmh is a common speed.

    Google Translator says: Привет. Программа САПР была студенческой версией устаревшего программного обеспечения, название которого я не хочу здесь упоминать. Если бы мне пришлось сделать это снова, я бы использовал SOLID Works или NX. Шатун был рассчитан по методу аналогии и сделан более жестким. Все поперечные сечения валов на 30-40% больше. Кроме того, толщина стенки глазка значительно увеличена с целью большей эластичности титана и за счет гнезда.
