Hey all, Greetings from Dubai. I have owned my 2014 Speedmaster for almost 6 years and she is running perfectly since I got her. Upgraded a bit in terms of pipes and direct air intake which improved the performance. Only downside is power and speed cap of 160km. I am contemplating upgrading however the new bonnivele/bobber/Speedmaster have great engines but small fuel tanks which brings me to my question: What is more economical both in money and time, upgrade my existing engine with all the other items that gets replaced in the process or get a new bike and change the tank? Thanks, Adnan
I did the motor up on my 865cc 2009 Bonneville America. Went for wiseco 904 cc big bore kit with higher compression pistons. Kit cost me $1200 Australian about three years ago when the Aus$ to American$ exchange rate was good. Now that kit costs $1350/$1400 . All up the rebuild cost me around $2500 including labour and dyno tuning. Now have close to 75/80 rear wheel horse power. It's your choice , buy a strange new bike or keeping something your familiar and happy with. I kept the standard cam's , as I wanted torque for towing. Here's my America and sprint with my two trailers in background.
Welcome Adrian. You can of course make improvements to your existing bike, but if/when you come to sell it you'll be very lucky to see any of the expenditure back. If you really love your current bike, that might be a price worth paying. Personally I'd put the money allocated for improvements towards a new(er) bike. As always, thats your choice, but ask any bike dealer which sells better, one in standard trim or a customised bike and I'd be very surprised if any of them went for the latter.
Adnan SH Welcome to the family. Big choice to make and only you can answer that. Some times we wish for something different. And if that is the case no mater what anyone says will influence that. Do hit the upload a file button bottom right corner and show the inmates your steed. Regards & Ride Safe. Joe.
Hello Adnan and welcome to the forum As said previously change the bike and if you have to refuel often from what I can remember when visiting Dubai fuel isn’t in short supply or expensive.
I did a Piston & Cam change on my 2007 Speedmaster and was really happy with it until it got totalled. Now have a T120 and have to say I dont miss the speedmaster as the T120 is pretty grunty and great on fuel. If you like pulling engines to bits I just put in a pair of Arias High Comp pistons, didn't see the point of new barrels for an extra 40cc's so the pistons are around £300 and possibly £30-40 for gaskets my cams came from a 790 engine but not sure if they get you a lot? As said before your choice but the new range are all £7-8k plus unless you look for a salvage bike and spend time/money getting it right.
Hi Adnan, Welcome to the forum, I have to agree with a few of the threads, and get yourself something with a bit more poke if that's what you want. Why is your speedmaster governed to 100 MPH?,
Hi Adnan and welcome to the Triumph forum. Re your question, your current bike has a power output and aerodynamics of a brick; so if you really feel the need to faster than 160 kms regularly you need a different style of bike, in my opinion. If you have the current bike's engine worked on, it will increase the feeling of power giving stronger acceleration but you need LOADS more power to counteract the effects pushing a totally non-aerodynamic shape through the air. People cleverer than I have calculated that to force an unfaired motorbike from 160 kms (100 mph) to 220 kms requires an increase in bhp of at least 50%. Truthfully a cruiser style bike is not styled or engineered to do speeds above 160 kms/hr. Have a look at a Triumph 1050 ST, it'll be as powerful and as fast as you'll ever need.
