70 can go easily but on single passenger.. drive slow, and follow traffic rules... avoid racing.....
i ve also visited back in 2015 on my 70 and also done Saif ul malook and Babusar top on it...
take extra spark plugs, puncture kit, raincoat.. and warm clothes.... and leave early morning almost 4am in morning so u can avoid trafic jam in Abbottabad... and u will reach easily before 1pm (including 2 r 3 stops), and preferably stay in Kahgan to avoid rush...from there u can visit all the areas easily... leave early morning for saif ul malook around 7am in morning so u can enjoy early views of the lake... and one important thing don't pack unnecessery items which u dont have to use...
